I have only ever found 2 things that really cost LESS in Canada than in the U.S.
--clarinet reeds and toothpaste (unless you buy U.S. toothpaste for a buck at Dollar Tree)
Pountine would make three

I hate to revive an old thread, but it would be fun to see a Canadian retailer speak up on this. I'm in the middle of trying to estimate how much it would cost to outfit myself once I do my certification. I've set up a basic low-ish end set of kit at several different places north (2 local shops and one online) and south of the border (2 online) and compared costs.
The best deal I've found choosing entry-level complete kit (stuff that I would consider actually purchasing) looks like I would still save a few bucks if I drove from Montreal to the south eastern US to pick it up MYSELF.
And here we have American shops trying to work with us to make the deals even easier.
Lessons in international economics aside, what gives?
I use MyUSaddress.ca- to take advantage of free US shipping offers and other price breaks, $5 / package and will hold without additional charges for up to a year. At an hour south - and close to places where I dive - it is a no brainer for me, quick hop across when next in the area. Prescott is a 2 hour drive for you from Montral, but there may be other services - including UPS stores - that are closer.
Where the difference is that my Canadian ones seem to spend more on big orders. I may sell a reg or bpw to a US customer where the Canadian will order both. Or multiples of both. Plus lights, fins, and other accessories.
Jim, I'll gladly swap their SCUBA costs with our pharma drug costs!
