Hat Sold Super Fast on eBay

Got a vintage NBA SnapBack hat and posted it on eBay for $60 and sold within 5 minutes. I also received a handful of messages of buyers offering to buy it for double that even though it already sold.

I told them it wouldn’t be right to the buyer to cancel and accept their offer. It seems like I obviously priced it too low and probably could have gotten a lot more but I’m not too well versed in hats as I’m an everything seller, so I just threw a price out there.

Has this ever happened to anyone else?
