I thought we agreed, order: RTCNXJFCR had not yet arrived and the deal was the end of February. If did not come until now, I doubt that will ever come (maybe I'm wrong)!
"End of February delivery" means they send out the miner by the end of February, not that you will receive it then. Just like the pre-production batch was Feb 10 delivery so they shipped them Feb 10 - 13 (my unit was sent out on 12th) and then it took some time to arrive. I expect the end of February units to be sent out before March 3rd (I have two units ordered in that batch).
You cannot expect a definite delivery date because various shipping options take varying amount of time.
