The best way to deal with scalpers is to not deal with them at all.

If nobody bought anything from scalpers on principle, regardless of the perceived necessity, then they would be unsuccessful and thus would be extremely scarce because their financial investment would go completely to waste. They'd be sitting on piles of ammo that they blew all of their money on, eventually forced to sell it off at a loss.

I can honestly say that I haven't purchased a single round from any scalpers, and I never will. I could honestly be completely without ammo and would sooner make due with melee weapons until I could buy ammo from a legitimate business charging the current market price than give one of those low-life crooks any money. It'll hurt them far worse than it will hurt me because I'm not the greedy fool who blew all his money on ammo hoping to turn a profit.
