Exactly. The others aren't even trying to expand to outside of the US, as far as any outsider can tell. It's frustrating to no end being a startup outside the US and having to rely on Paypal or a very slim selection of even crummier merchant providers here (Canada). I've had so many problems with the few providers that do offer service here that I grudgingly stick with Paypal now.
Amazon, come on guys, support Canada already! Help us out!
