Buying guides
How it works
Paste the ISBN from your syllabus and TextbookScout builds a direct link to that exact edition at eight retailers, so you can see who has it cheapest without opening eight tabs. Used copies routinely cost a fraction of the campus bookstore price, and the cheapest store is different for nearly every book — which is the entire reason this site exists. When the term ends, the buyback link compares offers from 30+ vendors so you can recover part of what you paid.
Common questions
What is the cheapest place to buy college textbooks?
It genuinely changes book by book. Used marketplaces like AbeBooks, ThriftBooks and eBay usually beat the campus bookstore substantially, but Amazon sometimes wins on newer editions and Chegg can win on rentals. See our full guide.
Should I rent or buy?
Compare the rental fee against the used price minus expected buyback value. Our rent vs buy calculator does the math.
Are international editions okay?
They are legal to buy and own in the US and usually contain the same content, though problem numbering can differ. More on that here.
When should I buy my books?
Two to three weeks before term starts, while used supply is deepest.
