Does anyone have experience purchasing a Groupon for a hotel stay, on the groupon.co.uk site? There are no Budapest deals showing up on groupon.com, and I am curious if it is possible to buy a groupon as an American in the US, but purchase on the groupon.co.uk site since I do see a Budapest deal there. Or is there another trick to seeing these deals? I'm also curious if I can use a groupon giftcard purchased here, to buy a deal on the UK site. Anyone had this experience?
