Hi, all
The Avalon says they will start shipping from April 15. And we need some time to switch my orders to buyer shipping address. So I will close my offer at 2:00 PM GMT April 12. If I will not sell till that time I will myself mine bitcoins on my Avalons

Avalon says they will not change shipping addresses.
There was a bit of drama with batch 1, where two parties wanted to change the address, then fell into disagreement. I would make plans for Avalon to continue their "ship to original" policy.
