I contacted Mona at dvdfab.com about this and she told me they don't take PayPal. Plain and simple. So I bought a pre-paid Visa card from a company named Greendot for $5.00. They're deal is a bit of a rip off in my opinion, and I highly suggest you buy a card, register it, use it, then cancel it after the sale is finalized. Because if you don't they start charging you by the month to keep using it. However, if you can't get a credit card, and you can afford the monthly fee I suppose that is another story... But I would keep an eye on them. Green Dot Corporation is a little on the greedy side.
There's tons of other cards like this from other companies. But if you're in the US, make sure the one you get is good for international online purchases. I bought one at my bank and it was for the US only. So then I had to buy another one, and ended up paying twice as much in fees as I would have if I had only had to buy one. Therefore raising what I spent for DVDfab by $10.00 instead of $5.00.
