Good discussion here. I refuse to buy from CT - the service is just so incredibly AWFUL, at least here in S'toon - but if they actually can be competitive with online pricing, maybe other tire retailers will be forced to match.
I know the shipping (and duty/brokerage) costs tends to even out the tirerack.com comparison, but for many people it's still a viable option. When I last ordered winter rim & tires, the cost was just over $800 - but with shipping & duty, etc., the final bill was $1200. Not cheap - until I got a quote from KalTire ($1800 for WS70s with 16" alloy rims). Unlike some other posters here, I've had nothing but great service from KalTire (first set of Blizzak WS50s), but man the prices are expensive. 1010tires - sorry, I know they are the forum sponsor - was nearly as expensive as KalTire, once shipping & mounting/balancing/hardware costs were included (that last stuff is complementary at tirerack).
Interesting comment that Canadian wholesale prices are still often higher than US retail prices. Can Cdn tire retailers do anything about that? Or is this just a case of more Canadians need to buy from the US until the price discrepancy narrows? One poster mentioned that the tire manufacturers don't care where you buy the tire (US or Canada), so long as you buy THEIR tire. Don't know about that - if the Cdn tire retailer has to pay the mnfr 40% more than the US tire retailer for the same tire, I'm pretty sure the mnfr would rather sell in Canada where there is more profit...
