I just knew I'll never understand the eBay mentality, but I have seen that happen several times.
It's as if a couple of guys are going for it trying to show each other how much they can afford to spend -
and how stupid they are!
(Too bad it never happens when I sell something!)
I gave up on eBay a couple of years ago; both buying and selling.
Why is it stupid if they have the money to blow on it? I wouldn't spend $200 plus on a carbine handguard, but ain't it great to live in a free country where folks can do so if they want?
