I fail to see why a t-shirt for $15 with no clever logo or design and a boring slogan is any sort of great deal.
I got my last political T-shirt for 50 cents. It reads:
McCain Palin
Unstable Unable
At least it rhymes and is printed in two colors. And it was only 50 cents.
I think using my body for political slogans is rather stupid, but it makes good underwear.
