Both my second individual purchases were auto-feedbacked within minutes. They were both 12:35 PST per the e-mails in my inbox.
Still only have one refund notice so far, but I don't see how they don't refund both if they did 11,995 the first time, then it jumped to 23,990 almost instantly when I refreshed it a few minutes after the first cap out. Then it went into the 40 thousands and was constantly dumping quantity back into the pool in tiny bits. I never saw the second listing until after I had bought two individual ones from the trickles back.
But now I have to figure out how I'm actually getting my money back. The refund e-mail is saying my e-mail address (I do have an active paypal, but I specifically used my credit card to avoid having to log into Paypal during the purchase check out sequence).
