Popped into WalMart this morning to print some wedding photos and while I was waiting I just happened by the vacuum aisle of all things. Anyways I noticed they had a Roomba, red one, for only $128, cheapest I've seen. On the back of the carton in small print with the Roomba Co. name etc it also had the WalMart name, so I'm figuring they must have made up a batch for sale cheap just for WalMart. Didn't come with any virtual walls though.
