I work for an importer so I know how the math stacks up.
It's true that consumers vote with their wallets often and order from outside Canada all the time, I do it myself on eBay all the time or direct from Redwolf or whoever.
The catch comes in when it is something like an AEG that you won't be able to import on your own, or something that requires installation that you cannot do yourself. If you walk into a stereo store with something you ordered in and and ask to have it plugged in you are doomed.
Most of the hardware I buy I get used from folks who are flip flopping on what they want to carry, hopefully they will pass the savings onto me!
