I messed up on eBay.
I sell watches that are old stock or have minute scratches on eBay.
I tried to be careful to put an item up on eBay.com/
This time I was selling a Casio Frogman.
After listing an item, even though I tried to be rather careful, I noticed the product name was somehow listed as GWF-1000RD even though the correct name was GWF-1000SR.
I took down the listing in order to fix it, but....
I forgot to select "Cancel bids and end listing early".
I was able to successfully sell it to a $300 bidder,... but I thought it would sell for a little more.
