Had a lot of problem with PayPal, great if you're a customer, not so great if your a business.
We got ripped off loads of times, people would order, then deny it. Because we didn't have
a physical product to deliver to an address, we lost out every time. I'd never use PayPal again.
If you have a business, and you send out more expensive stuff, PayPal will help you to get in financial trouble. Trust me was a Powerseller Untill 2008, I ended the Business due to charge-backs.
