The problem at least for me between .com and .ca, is that they seem to be fundamentally different sites with their own separate arrays of sellers and products that can be quite different from each other. There are many things sold on .com you simply cannot get from .ca, or even shipped to Canada from the .com site

Yeah, exactly. Each amazon site has 100% different products. You have to just search for the same product and hope it's there, or find something similar. Even more difficult when the other site is not in English.

Which is a bummer, because a lot of these sites are supported by affiliate links. When you go to your own amazon, you lose the affiliate connection and can't support the site that gave you the information.
