I was searching for a Cricut Gypsy for my wife and this seller had several listed in their eBay store. I started bidding on an item and notices I was out-bid at regular intervals.
I started checking the bidding history on several of their items and noticed a pattern. Several of the same accounts regularly bid on all of their store items. Some of the same bidders even out-bid themselves.
What kind of person would out-bid themselves? You guessed it. The kind of person that is trying to bid up their items.
