Actually, looking at my order history I ordered @ 12 Nov 2020 10:08:00 (Zotac GeForce RTX 3080 Trinity OC).
So how can someone who ordered @ 10:40 already have a ahipping email and I don't? My guess is they make it up as they go along... or as someone else said they worked backwards from the queue.
Relax, order time and shipping sequence don’t have to follow each other once stock is allocated.
There will be more than one person picking & packing each with their own list of orders.
