Even a few minutes past noon, there were still at least 5 $1k secondaries. I doubt there were barrels available. Had to ask myself what I'd do with 5 chips, so I passed.
I tried to get two racks instantly (had PayPal all teed up and everything). Then one rack. Nope. Then one barrel. Nope. At this point it was maybe 12:02.
Did not bother trying for 5 loose chips, as that quantity would be effectively useless to me.
