card shuffler's crap. for some reason i'm always tempted to try one out at every store and i'm always disappointed. i'm not some snob about card shufflers. unless you use more than 3 decks, something like this isn't worth it. for 1 deck, after you halved it for the shuffler, it'll drag one half, then the other. if you're lucky 5 cards will be mixed in with 5 cards from the other half.
talk about segmenting the market. this is the perfect solution to not offering pure coupons, not putting things in clearance, but still moving the junk they have.
