Gear in Canada can be between 20% to 75% more expensive.
Ordering from Canada won't ever be 75% more expensive. I'd say more like 20-30%. And ordering from the states can be 20-30% more expensive as well. Yes, a 300$ board in the states might cost 400$ in Canada. I agree. However, there are a few things you need to take into account when ordering from the US.
1. Shipping costs are much, much higher.
2. Once you get everything paid and shipped off, you need to take into account border/customs fees. Which, depending on the value of your package, can surprise you at your doorstep with a 10-50% (on top of the price you already paid) extra charge.
3. Even though the Canadian dollar is almost at par with the US dollar, keep in mind the exchange rate.
4. Expect a much longer wait to get your stuff, and add one day for border/customs checks.
Even though the listed price for a product WILL be less expensive in the states, they don't list everything you will be charged for.
Every opportunity I get, I order directly from Canada. Yes, the listed price will be higher, but I have WAYYY less expensive shipping prices, very fast shipping, and no border fees. I am also supporting a Canadian store. There are a ton of online shops in Canada with great prices, the difference only being the exchange rate. Search, and you will find them.
Of course, there is nothing better than going to your local boardshop, and supporting your local business.
P.S. I misread your post. If you are picking it up locally, then I'd say it would end up being slightly cheaper in the states.
