I've noticed that if I purchase a disc or 2 from Amazon.com, I get it no problems. But once I ordered 2 box sets and 2 books all in the same order and had to pay Duty when I picked it up.
I'm not sure if it had to do with the size of the order, or the items in particular, but I was pretty miffed.
Yeah, that's right....I said it! MIFFED!
