i always use the paysafecard here in the UK and from what i understand it should be available in almost every European country. They have store locator on their homepage, easy cheesy
you can use the paysafecard for basically all online games+shopping, just check their website, they have have most of them listed on there, i think you will find something to spend them 2 cards on hehe
Both the bulido and paysafecard Homepages indicate it is possible, just checked, but yes, it would not be a bad idea to contact both their customers supports.
