It happens all the time.
You will often find out later, when you get a second chance offer! LOL!
I've followed re-listed auction items and watched the same bidder or another bidder with zero or little feedback win, the same item again.
More than a few times on some occasions.
The shill-sellers-bidders are searching for a specific price point.
Without setting a buy-it-now price.
I know it's illegal, but really...
Who gives a rat's ass, as long as the price is fair?
I did a tonne of business with one Ebay power seller.
He was a great guy, great deals and great customer service after the fact.
I am positive that he was bid-shilling during his auctions where he listed numerous items starting at one cent.
The tell-tale-give away was the same phantom bidders kept winning many of his rock-bottom items where few or no other bids were made.
He had about 20 different shill-bidder accounts.
I followed the "winners" of the auctions on his site that I lost.
To see the feedback the left for the deal transaction.
There was none.
As I suspected.
If he had left fake seller-buyer feedback, he probably never would have had any problems.
A few months after I began dealing with the seller, I received messages from four angry fellow-Ebayers.
They also had figured out that this seller was doing some shill-bidding.
They wanted me to help take him down and to report him to Ebay.
I refused.
They were furious with me.
I told them that no one was forcing them to buy from that seller.
I took it that they were choked that they couldn't win decent items for less than a buck.
Well, they did band together and they reported the seller.The seller was suspended.
He was off for a few months, he's back and now he only lists buy it now prices.
I actually felt bad for the guy.
He always treated me right.
Realistically, I never expected to win items that had a street price tag of a few hundred dollars for a penny.
Obviously, other people did.
Oh, well...
