Strangely, I have three accounts

but for some reason wasn't allowed a card for 2 of the three of them (although when I asked for a card on those two I was under 18, so that may be why).
I think I may take your advice TS, it sounds very clever, and would make life much simpler for me, although - I'll have to wait until after Christmas as all my preorders are on the one card right now and I don't want to edit my billing information for every single one, so I shall definitely use your method once the year is over.
And thanks for moving the thread, I didn't actually mean to post it in there (think I was reading another thread in there prior to posting), so thanks

will try and remember which section I'm in before posting a new thread from now on
