I just received an email from B&H that my order has shipped UPS ground. That's certainly an improvement over their earlier estimate that it would be 4/30 for shipment.
No other info available yet, such as a tracking number. I ordered a 6core/16GB/512/D500, on 2/20.
Congrats. I'm still waiting for a 6c/16GB/1TB/D500 from B&H that I ordered on 2/4. The last message I got from B&H on 4/1 was that the item was still out of stock and that they "haven't yet received the merchandise from our supplier."
