This is probably a mistake but it shows up in my cart. If you want it at that price you better hurry.
edit: It looks like people aren't able to checkout at that price. I was able to get to the checkout page but didn't go farther because I'm not interested int buying. Sorry.
edit 2: It appears lots of stuff (everything?) is showing 50% off so there's a problem with the store. The checkout system is offline for now. This applies to the web.
