Thanks a lot for the heads-up on Mario Kart. Superstore in Orleans was sold out this morning but I was able to take the flyer and get it price matched at the Futureshop down the street.
I'm pretty sure there are no RCSS in Quebec. In the past, I've seen Maxi get the same deals on video games though. For example, the week RCSS in Ontario dropped the price on Pikmin by 10 bucks, Maxi had the same sale. Might wanna try there.
