Why are promo codes for iPhone & iPad apps only redeemable for people in US?? I wish Apple would start allowing them for Canada as well as other countries, I don't understand what the big deal is??

Anyone here know if or when this might become the case?

I agree with you completely.

Unfortunately it doesn't seem to be anytime soon. They've never worked in Canada

Whether it is too difficult to change them or they just don't care, who knows - but we're stuck with the setup the way it is for now.

What bugs me is that if I purchase an app in the US store, I can't review it in the Canadian store, and the same goes in reverse.

Anyway, don't hold your breath :P
