I know the price difference between the USA and Canada has been discussed before. What's interesting is how cross-border shopping actually helps the Canadian economy (but not individual firms).
What I like in that article is the calculator which takes into account your car's mileage and how much you pay for gas before letting you know if you're actually getting any savings going across the border.
Still, I'm thinking about a long-weekend trip to Spokane to do some shopping.
