I can't really remember too much of the US shops... as I'm not that much of a "shopping person"... but the most similar to Marks & Spencer would be something like Pennys (or is it called Jennys?)... TK Max is the same as TJ Max.

WalMart is like an Asda, just with LOTS more! WalMart has lots more clothes, toys, even pets, etc.

Tesco would be similar to Stop&Shop... just that Stop&Shop is WAY bigger!

Have you ever been to a proper Co-Op... one of those that sells everything in the UK? Well, that would be similar to Sears.

Didn't really do much food shopping in the US, as it's so cheap to eat out! Friendly's was a favourite!

Oh, and I found Burger King to be amazing in the US, whereas I can't stand it here in the UK!
