You're welcome, solocare! Using a paysafecard is really easy, it's something like a prepaid phone card, but you can use it for lots of things, not only for buying items in online-games. You can even buy things on amazon.co.uk.
Tony, you're actually right. I've never thought about it before. But, in any case, I'm using paysafecard for 'mini'-shopping. I won't lose much if something goes wrong. But it's really something to think about.
