Smokey,
Are you saying this didn't add up for you?
I'll try to answer your question without starting a $hit storm argument.
...
Single wall tipis made of Silnylon are obscenely expensive and that amounts to immoral profiteering by the manufacturers.
Well, now that I think about it, you could say that.
Whenever I want to avoid a $hit storm, I try to lead in with something a little more tactful.
Something along the lines of "no disrespect intended, but you're an a$$hole."
I try to always take the high road.
