I scheduled a bid on a designer bag on eBay with eSnipe. The auction just ended but I was not the highest bidder. The auction is "private" so the identities of the bidders are hidden. Almost immediately after the auction ended, I get an email through eBay messaging that the seller has offered me a second chance to get the bag at my max price. I am worried that I may be a victim of shill bidding but since the auction is private, is there any way I can find out for sure? I don't mind paying for the bag at this price but if I am being taken advantage of, I'd rather pass on it. Thanks in advance for any advice!
