Chatted with Amazon rep, only got $5 credit. I wonder how that one person on DDMS comments got $50.
The Indian fellow I was talking to kept on giving me his scripted message. I told him I had already printed the return label, packaged the items and left them for UPS pickup. So he said that if the trade-in was shipped already, then Amazon will ship them back to me once they receive them, and then I can decide whether I'd like to do a trade-in again at the new value. I told him that's completely unfair and the turnaround time is costing me money, so he offered me $5. I told him the hardship this is causing was much greater than $5 and that Amazon is welcome to send the items back to me, but they should still credit me for the full amount that they had agreed to. Eventually he caved and offered me a $50 credit.
