Return by December 28, 2026 for Fall 2026 rentals.

Late Fees

Books returned after the semester deadline accrue a weekly late fee of about 10% of the book's Brand New price, for each copy that is overdue. The rent you have already paid counts toward the book's replacement value (its Brand New price), so late fees stop once your rent plus late fees reach it. That replacement value is the most a rental can ever cost you. We email a reminder 48 hours before any charge, and any late fees are charged to the payment method you save at checkout.

Damage Fees

Books returned damaged beyond normal classroom wear may be assessed a damage fee, capped at the book's replacement value (its Brand New price). Any damage fees are charged to the payment method you save at checkout after we inspect the returned book.

Return Shipping

Returning your book is free: print a prepaid label (USPS or UPS, whichever is cheaper for your package) from your account's My Rentals page, whether you send it back early or on the semester deadline. Cancelling a shipped rental for a refund is different: there, the return label cost comes out of your refund.

30-Day Cancellation

Changed your mind? Cancel an active rental within 30 days of your order from My Account → My Rentals. Cancel before your book ships and it’s free; once it has shipped, we refund the rental price minus a 15% restocking fee and the return label cost, released once we receive your book. Shipping is non-refundable.
