Maybe Ebay is okay if you're a power-seller, but when I need a few extra dollars and sell something that'll fetch more then $20 because anything else is a waste of my time, AND I'm a "little guy", it can hit you hard.

Say I sell a game for $50. The final vaule fee for video game listings is 15% (yeah, it's more depending on what you sell.) Then I have to pay the paypal fee, 3.9% if I sold it overseas, which I probably did (2.9% otherwise.)
So I end up with $40.25. Yeah, that's nice, I needed $50 and got $40. I know there has to be A fee, because it is a service. I don't deny that, I just don't think it should be so much. If I don't have loads of money in my Paypal account, $10 can be significant. I'm not saying I'm poor and don't have 10 bucks, but ---damn.
A $10 service charge. Can you imagine a bank charging that much per transaction? Or ANYONE charging $10 for everything they do for you? Sure, Ebay isn't a bank. But they sure have a lot of customers, and they sure do charge a lot of money.
