When you sell, each transaction is charged 3.something % plus a small fee, 30 cents maybe? I haven't used mine in years for selling. But if you are getting the one that comes with the paypal debit card, each time you use the debit card, you get a % off on each debit card purchase. Sorry my info isn't any better, so you should really check the site. I've had mine for several years. I've been thinking of adding money to my account for the savings used with the debit card.
