I have a paypal(okay, I JUST made it. I've been using a friend's paypal this far) and even that you can't pay straight with it in Finland(yet) you can order some stuff from abroad, like amazon book store. I like to buy pretty obscure sciense books about insect flight muscles and stuff like that so it suits me fine. Food would be alot nicer, though.
BUT!
If you get a credit card that paypal approves of and find a place in Finland(or whatever country you might be in. Europeans seem to be mighty left out from this whole paypal-thing) that takes those cards you can also buy groceries.
