Yesterday someone made an offer on an item I've had listed for a few months. About 4 hours later, someone else made an offer of the same amount for the same item. DH was convinced they were the same person because it was the same amount. I couldn't understand why someone would do that. It's like bidding against themselves. Since I had two offers, I countered both of them and also sent offers to all the likers. One of the original bidders countered my counter. I waited to see if anyone else would do anything. Right before my counter was about to expire, the second offerer declined my offer. This person had her real name as her user ID. Then I accepted the bidder who had countered my offer. When I was printing the address label, I noticed that the buyer had the same last name as the person who declined. So it was at least a relative. Why would people do this? I think it worked against them as I thought there was more interest in my item than there actually was. Without the second offer, I might have accepted the first one sooner.
