Orders usually ship within 2 business days. Shipping costs within the U.S. are for media rate. If you need faster service please inquire. Large, heavy books or sets may cost more to ship and we will notify you of that before commitment. Insurance is included for items over $201. Less expensive items generally not insured. Buyer should request and pay for insurance for these if the risk of loss or damage in shipping is uncomfortable. International shipping costs have increased significantly in recent years. Please be prepared for a high cost. Shipping rates given are for an "average" book. Large or heavy books or sets will normally cost more - we try to note when more expensive shipping costs are likely in the description, but sometimes fail to do so until an order is received. This mainly applies to international shipping.
