Right of withdrawal for the sale of goods

Revocation right for consumers
(A ‘consumer’ is any natural person who concludes a legal transaction which, to an overwhelming extent, cannot be attributed to either his
commercial or independent professional activities.)

Instructions for revocation

Revocation right
You have the right to revoke this contract within 14 days without specifying any reasons.
The revocation period is 14 days with effect from the day, - on which you or a third party nominated by you, which is not the carrier, had taken possession of the products, provided you had ordered
one or more products within the scope of a standard order and this/these product/products is/are delivered uniformly;- on which you or a third party nominated by you, which is not the carrier, had taken possession of the last product, provided you had ordered
several products within the scope of a standard order and these products are delivered separately;- on which you or a third party nominated by you, which is not the carrier, had taken possession of the last part delivery or the last unit,
provided you had ordered a product, which is delivered in several part deliveries or units;
To exercise your right of withdrawal, you must inform us** (Andreas Fischer-Rödig, Erbprinzenstr. 11, 79098 Freiburg, Telephone number:
0761-4510578, E-Mail address: info@antiquariat-fischer.eu**) by means of a clear declaration (e.g. a letter sent by post, or an e-mail) of your
decision to withdraw from this contract. You can use the attached model withdrawal form for this purpose, which is, however, not mandatory.
You can also exercise your right of withdrawal online by clicking on a button labelled accordingly (such as ‘Withdraw from contract’ or similar)
on the AbeBooks/ZVAB website. If you use this online function, you will immediately receive a confirmation of receipt on a durable medium
(e.g. via email) containing information on the content of the withdrawal notice, as well as the date and time of its receipt.
In order to safeguard the revocation period, it is sufficient that you send the notification about the exercise of the revocation right before the
expiry of the revocation period.

Consequences of the revocation

If you revoke this contract, we shall repay all the payments, which we received from you, including the delivery costs (with the exception of
additional costs, which arise from that fact that you selected a form of delivery other than the most reasonable standard delivery offered by us),
immediately and at the latest within 14 days from the day on which we received the notification about the revocation of this contract from you.
We use the same means of payment, which you had originally used during the original transaction, for this repayment unless expressly agreed
otherwise with you; you will not be charged any fees owing to this repayment.
We can refuse the repayment until the products are returned to us or until you have furnished evidence that you have sent the products back
to us, depending on whichever is earlier.
You must return or transfer the products to us immediately and, in any case, at the latest within 14 days with effect from the day on which you
inform us of the revocation of this contract. The deadline is maintained if you send the products before the expiry of the 14 day deadline.
You bear the direct costs for returning the products.
You must pay for any depreciation of the products only if this depreciation can be attributed to any handling with you that was not necessary
for checking the condition, features and functionality of the products.

Criteria for exclusion or expiry

The revocation right is not available for contracts
for delivery of products, which are not prefabricated and for whose manufacturing an individual selection or stipulation by the consumer
is important or which are clearly tailored to the personal requirements of the consumer;
for delivery of products, which can spoil quickly or whose use-by date would be exceeded quickly;
for delivery of alcoholic drinks, whose price was agreed at the time of concluding the contract, which however can be delivered 30 days
after the conclusion of the contract at the earliest and whose current value depends on the fluctuations in the market, on which the
entrepreneur has no influence;
for delivery of newspapers, periodicals or magazines with the exception of subscription contracts.
The revocation right expires prematurely in case of contracts
for delivery of sealed products, which are not suitable for return for reasons of health protection or hygiene if their seal has been
removed after the delivery;
for delivery of products if they have been mixed inseparably with other goods after the delivery, owing to their condition;
for delivery of sound or video recording or computer software in a sealed package if the seal has been removed after the delivery.

**Standard Business Terms and customer information / data protection declaration

**I. Standard business terms

§ 1 Basic provisions

(1) The following terms and conditions of business apply for all contracts concluded with us as the supplier (Andreas Fischer-Rödig) via the
websites AbeBooks and/or ZVAB. Unless otherwise agreed, the inclusion of your own terms and conditions is explicitly rejected.
(2) A ‘consumer’ in the sense of the following regulations is every natural person who concludes a legal transaction which, to an
overwhelming extent, cannot be attributed to either his commercial or independent professional activities. The term ‘businessman’ refers to
every natural person, legal person or legally responsible partnership that concludes a legal transaction in pursuance of his/its independent
professional or commercial activity.

§ 2 Conclusion of the contract

(1) The subject-matter of the contract is the selling of products .
We sell the product under our own name on behalf of others, i.e. for an external party that owns the product in question. In this regard, we
play the role of a partial or total commission agent. In spite of that, we are a contractual partner who enjoys all the respective rights and is
subject to all the respective responsibilities.

(2) If an article is placed by us with AbeBooks or ZVAB, the activation of the page on AbeBooks or ZVAB shall involve the binding offer to
conclude a contract under the terms and conditions contained in the article page.

(3) The contract shall become effective via the online shopping cart system as follows:
The products intended for purchase are moved to the "shopping cart". You can select the "Shopping Cart" using the appropriate buttons on the
navigation bar and make changes there at any time.
After calling up the “Checkout” page and entering the required personal data and payment and shipping conditions, all order information is
then displayed again on the order summary page.
Before submitting the order, you have the ability once more to review or change any information here (you may also use the "back" button on
the Internet browser), or to cancel the purchase.
By clicking the “Buy now” button to submit the order, you declare your legally binding acceptance of the order which makes the contract
effective.

(4) The execution of the order and the sending of all the details necessitated by the conclusion of the contract take place via e-mail, in a
partially-automated manner. Consequently, you have to ensure that the e-mail address that you have deposited with us is the correct one, and
that the receipt of the respective e-mails is guaranteed. In particular, you have to ensure that the respective e-mails are not blocked by a
SPAM filter.

§ 3 Right of retention, reservation of proprietary rights

(1) You can only exercise a right of retention if the situation in question involves claims arising from the same contractual relationship.

(2) The goods remain our property until the purchase price is paid in full.

(3) If you are a businessman, the following conditions also apply:
a) We retain ownership of the goods until all the claims arising from the ongoing business relationship have been settled in full. The goods
subject to retention of title may not be pledged or transferred by way of security before ownership of the said goods changes hands.
b) You can re-sell the goods within the framework of an orderly transaction. In this regard, you hereby cede all the claims amounting to the
magnitude of the billing amount that accrue to you as a result of the re-selling operation to us, and we accept the cession. Furthermore, you
are authorised to collect the claim in question. However, insofar as you do not discharge your payment obligations in an orderly fashion, we
reserve the right to collect the claim ourselves.
c) In a situation involving the combination and amalgamation of the goods subject to retention of title, we acquire co-ownership of the newly
formed item. This co-ownership corresponds to the ratio that exists between the invoice value of the goods subject to retention of title and the
other processed items at the time of processing.
d) If you make a request of this nature, we shall be obligated to release the securities that are due to us, to the extent that the realisable value
of our securities exceeds the claim to be secured by more than 10%. We are responsible for selecting the securities to be released.

§ 4 Warranty

(1) The statutory warranty rights are applicable.

(2) If we notify you of this prior to the submission of the contract declaration and this has been expressly and separately agreed, the limitation
period for claims for defects in used goods shall be one year from the date of delivery of the goods. The above limitation does not apply:- for culpable damage attributable to us arising from injury to life, limb or health and in the case of other damage caused intentionally or by
gross negligence;- insofar as we have fraudulently concealed the defect or have assumed a guarantee for the quality of the goods.

(3) As a consumer, you are requested to promptly check the product for completeness, visible defects and transport damage as soon as it is
delivered, and promptly disclose your complaints to us and the shipping company in writing. Even if you do not comply with this request, it
shall have no effect on your legal warranty claims.

(4) If a characteristic of the goods deviates from the objective requirements, the deviation shall only be deemed to be agreed if you were
informed of the same by us before submitting the contractual declaration and the deviation was expressly and separately agreed between the
contracting parties.

(5)
Insofar as you are an entrepreneur, the following shall apply in deviation from the above warranty provisions:
a) Only our own specifications and the manufacturer's product description shall be deemed agreed as the quality of the goods, but not other
advertising, public promotions and statements by the manufacturer.
b) In the event of defects, we shall, at our discretion, provide warranty by rectification of the defect or subsequent delivery. If the rectification
of defects fails, you may, at your option, demand a reduction in price or withdraw from the contract. The rectification of defects shall be
deemed to have failed after a second unsuccessful attempt, unless the nature of the goods or the defect or other circumstances indicate
otherwise. In the event of rectification of defects, we shall not be obliged to bear the increased costs arising from the transport of the goods to
a place other than the place of performance, unless such transport is in accordance with the intended use of the goods.
c) The warranty period shall be one year from delivery of the goods. The shortening of the period shall not apply- for culpable damage attributable to us arising from injury to life, limb or health and for other damage caused intentionally or by gross
negligence;- insofar as we have fraudulently concealed the defect or have assumed a guarantee for the quality of the item;- in the case of items which have been used for a building in accordance with their customary use and have caused its defectiveness;- in the case of statutory rights of recourse that you may assert against us in connection with rights arising from defects.

§ 5 Choice of law

(1) German law shall apply. This choice of law only applies to customers if it does not result in the revocation of the protection guaranteed by
the mandatory provisions of the law of the country in which the respective customer’s usual place of residence is located (benefit-of-the-doubt
principle).

(2) The provisions of the UN Convention on Contracts for the International Sale of Goods are explicitly inapplicable.

§ 6 Protection of minors

(1) For the sale of goods, that are subject to the regulations of child welfare protection law, we only deal with contractual relationships with
customers who have reached the legally prescribed minimum age.
Any age restrictions are referred to in the respective item descriptions.

(2) By submitting your order, you assure that you have reached the legally prescribed minimum age and that your details as regards your
name and your address are correct. You are under obligation to ensure that only you or other persons authorised by you to accept the
delivery, who have reached the legally prescribed minimum age, can take delivery of the goods.

(3) As long as we are under obligation by the legal provisions to carry out an age verification, we instruct the logistics service provider
commissioned with the delivery to hand over the delivery only to persons who have reached the legally prescribed minimum age, and in case
of doubt, to request for the identity card of the person accepting the product for the purpose of age verification.

(4) As far as we show, beyond the legally prescribed minimum age in the respective item description, that you must have completed 18 years
of age to be able to purchase the item, the aforementioned sections 1-3 are applicable providing that instead of the legally prescribed
minimum age, the legal age must be reached.

Data protection declaration

Unless stated otherwise below, the provision of your personal data is neither legally nor contractually obligatory, nor required for conclusion of
a contract. You are not obliged to provide your data. Not providing it will have no consequences. This only applies as long as the processing
procedures below do not state otherwise.
“Personal data” is any information relating to an identified or identifiable natural person.

Responsible person
Contact us at any time. The person responsible for data processing is: Andreas Fischer-Rödig, Erbprinzenstr.
11, 79098 Freiburg Deutschland, 0761-4510578, info@antiquariat-fischer.de

Collection and processing when using the cancellation button
If you have entered into a contract via this platform for which a statutory right of cancellation applies, the platform provides you with a
cancellation function (cancellation button) through which you can submit your notice of cancellation immediately.
When using the cancellation function, your personal data (name, email address, details identifying the contract or part of the contract you wish
to withdraw from, and the time (date and time) of sending the notice of withdrawal) will only be collected to the extent that you have provided
it.
The purpose of data processing is to provide you with the statutory option to withdraw from your contract and to ensure the proper processing
of your withdrawal.
The platform operator collects your data on the basis of Article 6(1)(f) of the GDPR, namely the legitimate interest in ensuring the general
accessibility of the statutory withdrawal function on the platform. You will receive a confirmation email from the platform operator
acknowledging receipt of your notice of withdrawal.
The data is then transmitted to us by the platform operator.
If the contact relates to a contract already concluded between you and us, this data processing is carried out on the basis of Article 6(1)(b) of
the GDPR. Otherwise, data processing is carried out on the basis of Article 6(1)(c) of the GDPR, to fulfil a legal obligation to provide an
electronic withdrawal function.
We use your email address solely to process your notice of withdrawal. Your data will subsequently be deleted in accordance with statutory
retention periods, provided you have not consented to further processing and use.

Collection, processing, and transfer of personal data in orders
When you submit an order we only collect and use your personal data insofar as this is necessary for the fulfilment and handling of your order
as well as processing of your queries. The provision of data is necessary for conclusion of a contract. Failure to provide it will prevent the
conclusion of any contract. The processing will occur on the basis of Article 6(1) b) GDPR and is required for the fulfilment of a contract with
you.
Your data will be shared, for example, with shipping companies, dropshipping or fulfillment providers, payment service providers, service
providers for order processing, and IT service providers. We will comply strictly with legal requirements in every case. The scope of data
transmission is restricted to a minimum.

**Merchandise management **

Use of an external merchandise management system

We use a merchandise management system in the course of order processing for the purposes of contractual processing. For this purpose
your personal data as collected in the course of the order will be sent to
w + h GmbH, Emy-Roeder-Str. 10, D--97074 Würzburg

Use of PayPal
On our website we use the PayPal payment service of PayPal (Europe) S.à.r.l. et Cie, S.C.A. (22-24 Boulevard Royal L-2449, Luxembourg;
"PayPal"). The data processing serves the purpose of offering you payment via the payment service. By selecting and using payment via
PayPal, the data required for processing the payment will be transmitted to PayPal in order to enable us to fulfil the contract with you with the
selected payment method. This processing is carried out on the basis of Art. 6 para. 1 lit. b GDPR.
All PayPal transactions are subject to PayPal Privacy Policy. You can find these at https://www.paypal.com/de/webapps/mpp/ua/privacy-full
Use of PayPal Plus
On our website we use the PayPal Plus payment service of PayPal (Europe) S.à.r.l. et Cie, S.C.A. (22-24 Boulevard Royal L-2449,
Luxembourg; "PayPal"). The data processing serves the purpose of offering you payment via the payment service. By selecting and using
payment via PayPal, credit card via PayPal, direct debit via PayPal, the data required for payment processing is transmitted to PayPal in order
to enable us to fulfil the contract with you by means of the selected payment method. This processing is carried out on the basis of Art. 6
para. 1 lit. b GDPR.
For individual payment methods such as credit card via PayPal, direct debit via PayPal, PayPal reserves the right, if necessary, to obtain a
credit report on the basis of mathematical-statistical procedures using credit reporting agencies. For this purpose, PayPal transmits the
personal data required for credit assessment to a credit agency and uses the obtained information on the statistical probability of a payment
default in order to reach a reasonable decision on the establishment, performance or termination of the contractual relationship. The credit
report may contain probability values (score values) which are calculated on the basis of scientifically recognised mathematical-statistical
methods and include, among other things, address data. Your legitimate interests will be taken into account in accordance with the legal
requirements. The data processing serves the purpose of a credit check for contract initiation. The processing is carried out on the basis of
art. 6 para. 1 lit. f GDPR due to our overriding legitimate interest in protection against payment default if PayPal pays in advance.
For reasons that arise from your particular situation, you have the right to object to the processing of your personal data carried out on the
basis of Art. 6 para. 1 lit. f GDPR at any time by notifying PayPal. The provision of the data is necessary for the conclusion of the contract with
the payment method of your choice. Failure to provide such data shall mean that the contract cannot be concluded with the payment method
you have selected.

**Duration of storage **
After contractual processing has been completed, the data is initially stored for the duration of the warranty period, then in accordance with the
retention periods prescribed by law, especially tax and commercial law, and then deleted after the period has elapsed, unless you have agreed
to further processing and use.

Rights of the affected person
If the legal requirements are fulfilled, you have the following rights according to art. 15 to 20 GDPR: Right to information, correction, deletion,
restriction of processing, data portability. You also have a right of objection against processing based on art. 6 (1) GDPR, and to processing
for the purposes of direct marketing, according to art. 21 (1) GDPR.

legally.

arising from your particular situation to object at any time to the processing of your data with future effect.
