Well, a friend of mine is going to sell lots and lots of things from her collection (video games, My Little Pony dolls, and such), but there's one problem.
She's in Iceland. And PayPal doesn't care for Iceland. They refuse to let her transfer funds to and from her bank account.
What payment methods can she use to receive money from non-Europeans? Europeans can use bank transfers, but the rest of the world is screwed.
