Doesn't cost at all actually, for me. Sadly the issue is that the only reason I could get this type of card is that my account has a fair deal of services attached to it, most of which the average user would not have any use for, or indeed in most cases actually be able to get (very few people have bank account with business services after all). As for "prepaids" in Sweden, none are sold as far as I know, though I might be mistaken. One way to make "one-time" payments btw, just as an aside, is to just gift some subscription money to yourself and use that, tip it up as required. (this, of course, only solves the issue for those that don't want recurring costs, not for those with issues in regards to spreading their credit card info all over the net)
