I remember the first time I saw Skeletonwitch at a bar in Manhattan, KS, their shirts were $10 - $12. They're normal price now.
Bolt Thrower shirts at MDF were, I think, $15 each. Maybe cheaper, but they were definitely lower than normal. That was fucking awesome. I heard they printed their own stuff to keep costs down, though.
