they do charge the .25c but its on top of the listing price you provide. so if you set a price for $1.00, they will list it for 1.25. there's just a processing fee as they recieve your cards, processing and ready it for listing. the only thing is unless you pay the prime $1, it takes about 3-6wks for them to process anything you send them. if you have cards that you're going to get a few dollars for and just want to get rid of, its worth it, but if your sending commons, you're not going to get your moneys worth- remember on the finacial side of it, you're paying up to $15 for shipping and if you send in a dozen low priced cards, you'll just lose a few bucks. good luck
