Flingsmash (game is awful but the remote retails for $40 by itself) is on clearance at toysrus.com for $25 and is the same price in store. Online you are limited to one because of purchase limits but in-store I was able to purchase 4 for $80 plus tax because of their "Buy 1 get 1 40% off" promotion. Basically BOGO on the remotes, plus you might be able to get $5 for the game somewhere....(doubtful).
FYI, I left four in store at Columbia MO, so these are in stock. One easy way to check is to see if it is available for in-store pickup.
