I noticed the same thing. I believe sometimes the auctioneer gets going too fast and forgets about the online bidders.
As for the flywheels, I bought some, and some backing plates. After I receive them and check them out, I may have 1 or 2 for sale, depending on condition. I don't want to sell junk to someone, and I am not sure of the condition of any of the stuff.
I also bought what looks like a recovered seat for $115. The last one I had done was well over $200.
