Memo to Amazon: I don't like being penalized for working all day when music shopping

So, at work this morning I sneaked a peek at Amazon's MP3 store to see if they were pimping the new Madonna album, MDNA, for cheap. It was going for $7.99 (deluxe version, of course) … good enough. But I can't download it at my place of employment. Now that I've got home after a long day of work and finally had time to sit down, the same album is $14.99. Thanks a lot, bitches.
