Crazy priced advertisements used to catch my eye and make me laugh, but I am over it. The best part of capitalism is that people will pay what it is worth to them. In these cases, the likelihood is nobody will pay that much, and after a while of no bids, a dose of reality will set in. They will realize that their pricing is way off and do some research to figure out FMV, then make adjustments if they really want to clear it out (or they will continue to pile old boxes and junk on the glass and leave it in the corner of their garage or basement collecting dust for another 20 years...)
Now imagine the price if they had been told by someone that the "silverballs" were actually made of silver!
