I just wanted to drop a thumbs up into the thread here.
There was some miscommunication on the numbers of an item they had available. We managed to arrange for a substitute via their customer service and the day after I sent my final reply confirming the substitute would be acceptable, I had my order in my hands.
So from ordering on 5/16, we arranged a substitute for a portion of the order on the same day. I confirmed the substitute was acceptable on 5/17 and received my order on 5/18.
I'll certainly be doing business with Amagi metals again (and most likely again and again and again each time I mine enough BTC for more orders).

Thanks...
