Questions
Is the shelf valuation a guaranteed offer?
No. It is a free estimate based on current marketplace price data where available. You set the final price and receive that book price when it sells.
Can I list a whole box of textbooks?
Check up to 30 ISBNs at once, then list the books individually. Individual listings are easier for students to find and let each book reach the right buyer.
Does selling cost anything?
No. Listings have no seller fee or commission. When a book sells, the buyer pays for tracked delivery and you receive a prepaid label.
