[quote name='Badgun']I'm looking to buy one of the red DS for my wife because she wants to play Nintendogs. I already have the game, but I'd like to get the system with Mario Kart for me to play. Are these readily available and is anyone running them on sale?[/QUOTE]
circuit city has the 15% off codes off of purchases over $100 for the rest of the weekend(online and B&M) so that is most likely the cheapest place to get a DS. Although i think target may still have them for $100 but i havent actually seen any target that is running the sale but i have heard people talk about it on here.
Although you maybe can get lucky and get one off of ebay for even less(if you dont mind used)
