The high bidder made the bid on the day the auction ended. The bid was made around an hour before the end time. He (or she) won the item by $0.70. Seventy cents.
I can’t think of anything that would have caused (or justified) an accidental bid.
My bag of stuff has been sold for 21.50, the buyer has payed, and I have shipped. I am still earning a track record on eBay,so the money will get to me in about 5 days, and I will donate it asap.
