More About ThriftBooks
What ThriftBooks Sells and Who It Suits
ThriftBooks is the world’s largest independent online seller of used and new books, with more than 19 million titles available. Since 2003, the company has sold over 300 million books, making it a strong choice for budget-conscious readers, collectors, educators, and anyone looking for a wide selection of fiction, nonfiction, and specialty titles. The site’s personalized recommendation engine helps account holders discover books tailored to their tastes, which is especially useful for frequent readers or those exploring a new genre.
Membership and Rewards Programs
ThriftBooks offers several ways to save beyond everyday low prices. The ReadingRewards loyalty program lets customers earn points on every purchase and redeem those points for free books. The ShareBookLove Tell-a-Friend program provides another path to free books by rewarding customers who refer others. Educators, librarians, and homeschoolers can join ThriftBooks 4 Teachers for free after verifying their status online. This program gives an everyday benefit of every fifth book free, plus an elevated status in ReadingRewards, making it a valuable option for schools and libraries.
Buyback Program
For those looking to declutter or offset costs, ThriftBooks BuyBack allows customers to sell selected books back for cash or store credit. This program supports a circular economy approach, letting readers recycle their collections while saving on future purchases.
Recognition and Customer Experience
ThriftBooks has earned the 2025 Best Online Shops recognition and the 2025 Best Customer Service award, marking seven consecutive years of that honor. Its Trustpilot score is rated “Excellent” at 5 stars, based on more than 2.1 million customer reviews. These recognitions reflect the company’s commitment to a best-in-class e-commerce experience, from easy browsing to reliable order fulfillment.
Who Should Shop Here
ThriftBooks suits anyone who values affordability and variety in book shopping. Casual readers can find cheap used copies of popular titles, while serious collectors can search for hard-to-find editions. Teachers and librarians benefit from the dedicated educator program, and environmentally conscious shoppers can participate in the buyback program to extend the life of books. With no membership fee required for basic shopping, it is accessible to all.
How to Use ThriftBooks Promo Codes
- Pick an offer on this page and select "Show Coupon Code" to reveal the code. Offers without a code apply on their own once you follow the link to ThriftBooks.
- Add the items you want to your cart, then open the checkout page.
- Paste the code into the promo code or discount field and apply it.
- Check that the order total drops before you pay. If it does not, the code did not apply.
If Your ThriftBooks Code Will Not Apply
Most codes fail for one of four reasons: the offer expired, the cart is below the minimum spend, the items are excluded (sale and clearance stock often are), or the code is limited to new customers. Read the offer terms on this page first, then try the next code on the list.
Stacking Codes
Most retailers accept one promo code per order, and ThriftBooks is no exception unless an offer says otherwise. When you have several codes to choose from, apply the one that saves the most on your specific cart rather than the largest headline number.
