Super Meat Boy's XBLA launch sale will conclude in six days, on November 21. After that (barring deal of the week promotions) the difficult and rewarding platformer will cost $15/lb. (one pound minimum order). Even if you have a backlog of titles at the moment, it's worth picking up the excellent game for $10 and putting it in the Xbox freezer until you're ready to play. It won't get freezer burn and thaws just as fresh.
