Let's see, I just bought a Canon EF 85f1.8 from Allens Camera in Levittown, PA (
www.allenscamera.com). I was down in the US for a 3 day business trip so had a $400 exemption. I paid U$340.00 shipped to me, since the value of the lens was under the exemption, it was brought in duty and tax free....but even if I had paid GST & PST (BC) on it, that's 12% or $369.60, shipping would have added maybe $10 more if it was sent USPS....grand total about $392.00 tax paid, to me. Visa on the day I ordered was at par on the exchange, so no problems there. Oh, forgot the $8.00 Canada post charges, so an even $400, delivered.
Henry's has the same lens for C$549.00, Camera Canada is $542.00, add taxes then they're $ 614.88 and 607.04 respectively, not to mention the shipping, so another 20-30 bucks on top of that?... so why would any reasonable person be willing to spend the extra $225-300 to support their local merchant? I'm most of the way to almost buying another 85mm f1.8 for that price difference!
Yes, body prices are comparable, (not when I got my 10D & 5D, was close on the 40D), but for the most part, US prices are so much lower than our's that it makes no economic sense to buy locally. I have to sell a lot more images to make up that price difference, money I could easily spend on other things..like diapers and baby wipes for my new son!
The only break I ever got buying Canadian was my Z3100ps, at the time of purchase (unfortunately before that huge price drop), I got mine for about $2000 below what it was selling in the US.
