I carry an Amazon Canada Rewards Visa card primarily because it does not impose any foreign transaction fees on foreign purchases. Having one is very handy for us. For example, I recently added the Amazon card to our Holland America shipboard accounts as they're are always kept in US dollars. I won't get dinged an extra 2.5% as with most every other Canadian credit card.
But I can think of one place where the technically savvy behemoth could concentrate. Well, I guess, in actuality, it is Chase Canada which much move into the modern era. Although I love the card there is no way to turn off paper billing! This is no longer 1987, guys. Get your act together.
