Stop assuming we're all from the US here

Very often I see posts and the replies mention the likes of Dollar Tree, Wallmart, costs in dollars, etc etc. While I understand a large amount of people are from America, we aren't all. I've seen posts where people have specified where they're from and people have still commented to just go to Wallmart or just go buy a $0.88 cheapie or whatever. I myself have posted about where I live and Amazon don't deliver to my country and got at least three replies 'just order off Amazon'. I mean really people. Read, and stop assuming.
