OK, I normally don't do the pre-order thing, but this time I might make an exception. DisneyStore.com is offering a 3-pin set with the pre-order of UP. The pins actually look pretty decent. Heck, if not at least you could trade them. I don't know if you can get this deal in the local stores or not since I have not been there yet.
