Woot.com, the Internet masters of the one-day-deal (aka “buy this crap now or you’ll never be able to again!”) now have a t-shirt arm. Shirts are $10* on their first day and then $15* until they stop selling so well and are discontinued. So we’ve all missed the $10 price for this nice Tetris+Chicago mashup, but it’ll be available as long as you keep buying it. Yes, you.

* shipping included, which is nice.
