$10 a piece for tapco mags is what I paid, glad I bought mine before people lost their minds. Also lucked out and found a guy a couple years back that thought he was selling 75rd drums for a $100, turns out he was selling 100rd drums for $100.
Buy when it's calm and slow, then you can sit back and laugh at all the stooges that get caught up in the frenzy and pay 3 and 4 times what things are worth.
They only have themselves to blame, no one is forcing them to buy. And if prices don't return to normal, we have them to thank/blame.
