For me a "private listing" auction on Ebay is a big red flag and is an excellent cover for a seller to shill bid their auctions. I don't know why Ebay allows those type of auctions.
Shill bid meaning to artificially increase value? How do folks get a private listing anyway? This kind of info is helpful. I'm not questioning this seller's integrity, I'm just trying to learn when I'm in over my head, when to stay away and when it's okeedokee. Thanks
Shill bidding is when the seller bids on his own auctions for obvious reasons. It is against the Ebay rules but some sellers get away with it.
Bid what you feel comfortable with or buy a BIN listing if that is a better course. No one can increase your price higher than you will let them
