As a seller, you MUST have a credit card listed with Paypal or you cannot receive money - plain and simple. People don't realize this because they let you do it without a credit card for about $2,000, then they close you down until you list a credit card.
Paypal is just about necessary to do business on eBay, IMHO. So many people won't bid if they can't pay via paypal, you lose money.
I use it, I generally like it.
BUT...God help you if a buyer complains 'merchandise not as advertised'. They LOCK your account. Period. Frozen. No money in, no money out. Try to run auctions that way. They say 7-14 business days to resolve a dispute - BS. Took well over three months in my case. And I lost big time to a crook. And FORGET about getting anyone at Paypal who will say anything other than 'Sorry you feel that way'.
I hate Paypal. I use them - really, I have to. But I hate them. I think they're shysters and crooks who have a nice niche for themselves and are making money hand over fist. Bully for them, but the day someone else gets their act together enough to compete with them, Paypal is over. They really are bullies and crooks, but they are the only (real) game in town right now.

PS - One tip is to sweep any money out of your account each day. Don't let it ride as a positive balance. They can't lock what they don't have. However, they did lose a court case - for awhile, they WERE locking up people's bank accounts - even their checking accounts. And the banks let them do it. They lost in court.
