Our standard domestic shipping rate is for USPS Media Mail shipments weighing up to 2 lb. Books are packaged in bubble-pack envelopes or a cardboard box with moisture protection. International shipping rates are for packages weighing up to 2 lb (0.9 kg). Heavier or oversized items may incur a shipping surcharge, which will be stated to the buyer before finalization of the transaction. Shipping charge may be reduced on some books weighing less than 1 lb to U.S. addresses. International Priority shipping charges may be reduced on books that fit in a USPS small flat-rate box. International Standard (First-Class Package International) shipping charges may be reduced for a second or more books if the total package weight does not exceed 2 lb. Shipping speeds are estimates based on carrier delivery times and cannot be guaranteed. If your order will pass through Customs, please expect a delay. Any applicable Customs duties or brokerage fees are the responsibility of the buyer.
