There's a few different twists to this so read on.
Its a promotion run by HP (see below for the promo link). If you buy 5 of any of the valid toner catridges they'll give you a Wii, alternatively if you buy 15 of them you can get a 22" screen or a presario 710TU. You can also take $100 or $350 cashback respectively as an alternative but I reckon the goodies are more appealing.
Being run by HP it means that the promo is most likely on offer at ANY of their authorised distributors not just office works. I havent been able to find out definitively whether thats the case but you could always just call them if you wanted an answer.
Now the toners arent cheap - so no... its not a cheap way to get a Wii but I've only checked one of the eligible models.
