New customers are asked to provide payment upon ordering. Institutions will receive items on approval with a 30-day invoice unless other arrangements are made.

Items may be returned within 30 days of receipt, in the same condition, for any reason. All books are guaranteed as described. Complete instructions for returns will be found on our Shipping & Returns page.

Payment methods accepted through our online store are restricted to credit cards (excluding UnionPay), Apple Pay, PayPal, and Venmo. Some additional restrictions based on the customer’s home country may also apply.
