I have a little experience with GB. It’s interesting that the high bidder has no feedback and placed the current high bid on July 1. That doesn’t automatically mean anything, but it also might be a textbook schill bid, or somebody bidding that won’t follow through after the auction is completed. All that said, it does take another bidder to drive the bid up. At the end of the day you won’t really know that the transaction has been completed (and thus, a value set) until feedback is left.
