I am sure the guy with the poster board is comparing his purchase of a neon-yellow poster board with the gun he purchased on the black market.

Black market, they come to you. You give them cash, you get the item. No tax, no waiting, no hassle, what you see is what you get.

The guy probably then went to Woolworths and found the poster board section completely decimated. Then he went to Save-on-drugs and found they didn't have any neon-yellow. So then, he marched, half way down main street to the Michaels to finally pay too much for a poster board.

That has to be it.
