Basic shipping in the United States is free. (If you’re super-eager to get your rewards, you can upgrade to a higher shipping class, but you’ll be charged accordingly at the time of fulfillment.) For international backers, you’ll pay the shipping costs at the time of fulfillment, but we’ll subsidize $10 of your basic shipping cost. (In other words, if the cost to ship is $32, you’ll pay $22.) Warning: international shipping is expensive. We don’t have any control over that, and we can’t accurately predict what shipping rates will be at the time of fulfillment. If you’re an international backer and have questions about shipping rates, you can visit the USPS website to get an estimate. We anticipate—but cannot guarantee—that our books will weigh about 1.5 pounds (0.7kg), but they are subject to spec changes, stretch goal upgrades, and the weight of packaging. Please also be aware that you may be responsible for import duties, and that we must comply with international law and cannot mark your reward as a gift or as a zero-value item. Duties are not included in your shipping charge.
