One of Target's weekly deals involved selling the Nintendo Wii system for $50 off. Before you go running off though, bear in mind that this is described as a legacy console - according to Target, that means the bundle comes without Wii Motion Plus. Wii Sports, a Wii controller, and a nunchuck attatchment are included in the bundle.
If that's not enough to stop you from purchasing a Wii at a pretty darn low price, then head over to Target and pick it up! Offer ends at the end of this week.
