PayPal is a lot harder to deal with now. In August, PayPal announced they have lost $231 Million since they started. The last thing they can afford to do is refund people.
I'm not saying PayPal will not refund, but in one case they waited 51 days before returning the money. PayPal does this because they make interest holding the money.
If you are in the US.. do not buy from these guys unless you are prepared to lose your money. There are better safer sources to deal with
