My $1000 savings arrived today
UPS just dropped off my 225/45R17 Blizzak winter tires from US online tire retailer The Tire Rack. Total charge in CAD including tax, duty, brokerage, currency exchange, VISA exchange fee, provincial tire fee, and shipping was $627.62. Delivery took 7 days. My neighborhood Tirecraft is installing them on Friday for $100 + tax.
Before my order I got a quote for Blizzak tires from a local Kal Tire. About $1,750 installed. In short, buying my tires online from the US has saved me over $1,000. The delivery man commented that he had also recently bought his tires from Tire Rack and had another order from them in his van waiting to be delivered to someone else.
The only way we will get lower prices in Canada is to buy elsewhere.
