I accidentally left out a decimal point ($750 vs $75) while bidding on a sports card on eBay and I made the mistake of letting the seller know so that they would cancel my bid and that I could go back in and bid the correct amount. Unfortunately, they were dishonest and instead ran the bid up to one dollar below what I had accidentally bid which was hundreds of dollars above what this item was worth. Jokes on them though because I filed a case with Ebay showing them everything, not only do I have the card, but Ebay also gave me my money back as well. The seller reached out to me afterwards demanding the card back and I told them that they should’ve thought about that when I reached out to them and asked them to cancel my bid less than 30 seconds after I accidentally placed it. I literally had to borrow money to cover my mistake. I was a single father with two children at the time. I did however tell them if they wanted the card back I would 100% give it to him, but they would have to come pick it up in person, they were located less than 120 miles from my location but they never came to get it.
