Wawa is a convenience store like 7-11, although not with as great a range. They are mostly a Pennsylvania and Delaware thing. I think there are a few in New Jersey.

I bought the guy a few pairs of socks because I realized I don't know his shoe size (which I would have to, to make socks). I might ask him about that, although I was thinking they'd be a surprise, which they can't be if I ask him.
