The $100 buck minimum bid and $10 minimum increment with the number of chucks available makes me suspect many wont sell on the 3rd.
The seller should have sold these across several auctions and had a lower minimum bid and increment and tried to encourage bidding. These guys who act like they're selling their own stuff are a hoot.
They're cheap chucks. I'd have taken one at 50 and maybe 75 bucks because I dont have a 4 jaw chuck for my lathe yet
