ABE Books is a marketplace for vendors. The problem is that ABE Books accepts all vendors, honest and dishonest alike. You should research any vendor on an independent site, like Google, Yelp, or SiteJabber before placing any order. ABE Books is honest but many vendors are not. I have used ABE Books for years and I have been cheated about 15% of the time, not by ABE books but by the vendor. However, ABE Books will NOT help you if you are cheated by one of its vendors. Do your homework first.
