Where can I find really Expensive / Exotic Candies?!

I'm looking to get a gift for a friend with a sweet tooth, and I don't want to just give them plain old Hershey's candies or the normal crap you can buy at a store. I want to give them something special they haven't had before.

I was hoping to find some really high quality, exotic candies online, but I really don't see anything special anywhere I've looked.

Can anyone recommend a website that has really high quality exotic or imported candies? I'm willing to spend a lot of money for something that will be memorable.
