Unfortunately, some books get manhandled a bit in shipping/storage! If you’re not terribly concerned with the books you read being in pristine condition, this is the offer for you.
The books may have dinged corners, scratches on the cover, flaking color on the edges, bookstore stickers, very minor water damage, or other problems that would prevent them being offered as “new”. No missing pages or anything that would render the book unreadable.
Stock of damaged books varies! Anything the store allows you to purchase should be considered ‘available.’
