Have you been to one before?
I visited the UK over the summer, and I went to so many nice bookstores there! My favorite was Rare Birds Books, a woman-owned feminist only selling books written by women. Everyone there was so nice and we had a great time chatting about books. I found out they now ship internationally! I don't mind paying a bit more for shipping to support a business like this.

There was one in LA on Westwood near UCLA for years. Finally lost their lease sometime in the 2000s and was replaced by a boxing supply store. Oh the irony!
