Question About Ordering Something from England?

Ok so I was just wondering…I live in America and there is this store over in England called Tesco and I was just wondering if I were to order Just Dance 3 online from them…like would they be able to send it???
Also with it being a game from a foreign country would it work on the American Nintendo Wii???:
(I have the American version of Just Dance 3 but it sucks and doesn't come with the extras)

Can't you get it from Amazon?
Tesco would send it, I imagine but you will have to pay currency conversion and postage.
