I'm sure many have a similar story to this...
So my dad calls me last week to invite me to an auction with a handful of guns/ammo being among the items up for bid. I kind of had my eye on a couple pistols, but ended up skipping out with other things on my plate.
He called to let me know what the pistols went for, and the deals weren't good enough that I'd have won them. But then he tells me that a like new Colt AR-15 went for $400. That's right, $400. Unfortunately, he's not really into the whole firearms thing enough to know market value. I told him that at that price, we could have moved it along in a couple of days for a $500 profit (that is, if I wouldn't keep it for myself).
Oh well, opportunity missed. Who knows what it would have gone for if there was one more interested party.
