ThriftBooks is the world's largest online independent used bookseller, founded in 2003 in Seattle, Washington. The company processes and lists millions of secondhand books, offering them at significantly reduced prices compared to new retail. ThriftBooks sources inventory from libraries, bookstores, and donations, grading each book's condition from Acceptable to Like New so buyers know exactly what to expect.
The platform offers free shipping on all U.S. orders of $15 or more with no membership required. ThriftBooks operates a loyalty program called ReadingRewards, where customers earn points on every purchase that can be redeemed for free books. The company emphasizes sustainability, having saved hundreds of millions of books from landfills since its founding.
