Go to yahoo search for grouponuUK the British are buying groupon deals by the thousands I never knew knew they were such big spenders actually more than Americans from what I seeing ;-)
Sentiment: Strong Buy
I think the group buying concept is still relatively new in that part of the world. Competition is not as strong. I've lived in the UK before and they don't have the kind of choice that we have when it comes to shopping.
The Groupon in Italy is huge too... Traveling and food deals are excellent!!
