The textbook rental check-in deadline for summer course materials is August 12, 2020. The spring deadline was June 1, 2020 and has passed.

Please check your Colorado.edu email for more information or contact [email protected]

Should you wish to send your books back by another shipping method, please mark the package as follows and be sure to include your full name and IdentiKey user name (not password) with your books:


CU Book Store
Attn: Rental Returns
36 UCB
1669 Euclid Ave.
Boulder, CO 80309

All packages must be postmarked by August 12, 2020 to avoid penalty. We strongly recommend that you ship your parcel with tracking and insurance to protect against lost and/or damaged shipments. If you use the prepaid UPS shipping label provided above this is not necessary.

If you choose not to return your rental books, they will be converted to a purchase and your student tuition and fee bill (where applicable) will be charged the difference between the rental and purchase price. You will not be charged any additional late fees.

Please note that the CU Book Store’s rental prices are low in many cases and the difference between your rental price and the purchase price may be quite large. It is recommended that you return the books to avoid additional charges.

Please allow 4-6 weeks for your rental books to be processed after the shipment is received at the CU Book Store. Please reach out to the CU Book Store with questions at [email protected]

Textbook sellback at the CU Book Store will be offered when the physical store reopens and information will be found here. If you include any textbooks that are not rentals in your shipment, they will be donated.
