Your sales will definitely go up, as many people (including me) won't pay any other way. It costs money, but I think it works out in the long run. I sell a lot on ebay, have 22 auctions running right now...

Might depend on what you are selling... Smaller ticket items (under $100 or so) definitely work better with Paypal. Many folks might not mind going to the bank when buying big ticket stuff...
