depends on if you're gonna be selling a lot of stuff. If it's a few small payments, a free account will do.
I would just go all out and sign up with a basic account which requires your checking account and you can also but in a back up credit card. Paypal accounts are free but you need the right stuff to just sign up. You can send, receive, or transfer money with a basic account. Paypal how they make their money is taking 3% of the money that goes into your account after each transaction. So if your buying or selling go with paypal secure, and it should be the only thing you use to buy or sell with.
Yeah I'll think I'll go with either bussiness or premier cause it takes less cash off when you recive.
