If they should or shouldn't advertise in that magazine is neither here nor there. I think I can safely assume that a large portion of the user base reading reptile magazine is Americian. The Magazine is published out of the US, it is an Americian magazine and as such I don't go looking in an Americian magazine for Canadian content. If I'm looking for Canadian content, then I'll look for a Canadian magazine.
