From shelf to price comparison

Three steps to check a book

Scan the exact edition, compare the available choices, and continue with the vendor that fits your needs.

Point your camera at the ISBN barcode. You can also enter the ISBN manually when scanning is not convenient.

Switch between sell, buy, and rental results without searching separate websites one at a time.

Open the vendor's site to confirm the quote, condition rules, shipping details, and payment terms.

Built for real-world book searching

Book titles can have several editions and formats. Scanning the ISBN helps match the copy in front of you instead of relying on a title alone.

Save books to favorites so you can return to them without scanning again.

Look at selling, purchasing, and rental options from the same app when those prices are available.

Price is only the starting point. Condition requirements, quote expiration, shipping, and vendor minimums can affect the final value.

One scanner, several use cases

Use BookTrapper when you are clearing a shelf, comparing a campus-store offer, or evaluating books for resale.

Compare textbook buyback options at the end of a course or semester.

Check a barcode while sourcing, then use the web bulk tool for larger ISBN lists.

Look up school books before buying another copy or clearing older editions.

See whether used books have an available offer before donating or recycling them.

Start with the next barcode

Compare available book prices from your phone, then verify the vendor's current terms before completing a transaction.
