For those that missed the original post but are offering bad takes anyway....
The OP originally had a mixture of 22LR ammo...various brands (Federal, CCI, Remington, etc). 4050 rounds total. He originally wanted $800 for the lot, or about $.197/round. The cheapest 22lr on ammoseek right now is $.197/round...then you pay shipping on top of that (and one retailer is charging a $5 handling charge in addition). The OP questioned in his original post if he was too high or not.
At the first sign of blowback regarding his price (which has been frowned on in the past), the OP immediately lowered his price on the lot to $400, or about $.099/round. A pretty decent deal at current prices. Let's not forget, and this is important...ammo is "previously purchased", not "used". No one's "gotten the good out of it" already.
Capitalism was working, but, the conversation became a shitshow regarding him requesting the buyer paying the 3%, which the OP was clear about in his original post, so the OP pulled his ad completely.
So, instead of someone getting 4050 rounds of 22lr for $412 (or possibly lower depending on negotiations), no one got a decent deal, and the site missed out on some money too.
I don't know the OP, and I don't run this site. However, it seems to me he was playing by the rules, but maybe his crime was being only a seller on the site...which isn't part of the official "rules" of the classifieds at this time.
