Prefer local but at the end of the day price is all I care about. I've been shopping around for the best price and so far Tire Rack seems to be best, and considering Canadian tax, when buying front and rears, I'm saving like 100 bucks over the best local price so far! If buying from the US I'd be shipping to Niagara Falls and smuggling so tax is not a concern.

My car's an E30 so rears are for the BMW. So far the best prices I've found:

US:
tirerack
rx7 front: 135 USD
e30 rear: 157 USD

Local
unauthorized
rx7 front: 195
e30 rear: 224

northern:
rx7 front: 210
e30 rear: 225

 

are u factoring in exchange rate? the site doesn't do that for you.

 

Exchange and shipping, works out to be around 100 bucks cheaper, even more for the more expensive shops. I'd prefer to support local guys but that's too much.
