Looks like folks are trying to dump guns they paid too much for.
Many are not happy. I've dealt with it a few times already. Folks overpaid in anticipation of "the ban," and now they've got to free up the cash. They are not happy with the offers they're getting.
"That's one third of what I paid back in December! You people are ripping me off! These are rare! Just like the...the...14 others you've got in stock now. Um. Hrm. Well, you're still jerks for not giving me twice retail for it! ☠☠☠☠☠☠!"
This summer is going to be a buyer's market for much of that stuff.
