lol, no Canadian discounts if you order from Stratified. Even if you can change the rates to CAD in their site, it's just a "estimate conversion" to help get an estimate. Once you pay, it's still going to be USD prices and whatever the real exchange rate is.
If you're within Canada or same province, you'll get dinged with the taxes too. A real kick in the nuts for sure... but they're a reliable company and offer good tunes. I'm tuned by Stratified.
Ultimately, I guess they're just trying to protect themselves because they don't want to lose out when Americans are buying all their tunes while the Canadian dollar is plummeting.
