Ebay is
tinkering with ways to keep bidders identity anonymous.
Some of the finished auctions you may look at don't show the actual sale price either, unless you actually click on the completed auctions.
Another new scammer trick (it doesn't work if you have any smarts) is to list a totally restored car (scam auction) and put in the heading "ignore bids on this car. I'll still sell it to you for $6200 no matter what the amount is bid". I've been reporting 5 to 10 of these every night. There are some others. Like auction # 150155276891 for a totally restored 69 GTO Judge for $2900 buy-it-now. Yeah right......
