Many times on this forum I have referenced a crazy estate sale that I attended back in 2016 or so. The prices were favorable and I bought five handguns including a NIB 422 and a NIB 2213. There were boxes overflowing with magazines and accessories and the estate sale company was selling entire boxes for $10-$20 just to clear things out. I bought a bunch of BHP mags and left. Of course I got home and realized each of the S&W pistols I had bought had only a single magazine. I ran back to the sale to find that someone had purchased all of the remaining firearm accessories. Big regret. Luckily, the local market was soon flooded with 2213 magazines for the next several months as people sold off their finds from the sale on Armslist, etc. I ended up picking a few up for what would be considered a great deal, but the sellers made a killing.
