I'm not a big traveler, but I have been around enough to know that you don't really want to buy anything at the airport.  A packet of peanuts for $5 is not my cup of tea, and neither is a $3 cup of tea.  You'd think that Best Buy Express, Best Buy's gadget vending machine, would be insanely expensive.  I would have, at least. 

As it turns out, the prices are actually the same prices you get at the normal Best Buy.  You know, a little overpriced, but not airport-level overpriced.  Color me surprised!

I do have to wonder just how much stuff gets sold at one of these machines versus, say, a normal vending machine with food inside, and what the profit margin is.  It can't be expensive to operate one of these, so I'd imagine they wouldn't have to sell much to break even, but who buys an impulse Nintendo DS at the airport?  Or digital camera?  I could understand magazines or books, but an emergency copy of Brain Training seems a little crazy to me.
