That was the AMD Brexit payback. The card showed instock for an instant until the webpage update to GB, As the alerts kept coming through I fired up an Ireland VPN and all three cards + most of the CPU's were available.
Set the VPN off, clicked the direct link again and it once again showed stock for a brief second as GB loaded.
Back to Ireland VPN, 2 of 3 cards in stock with 2 CPU.
Did anyone actually see these is stock in UK, from what I can see they were EU only, probably due to the complexity of UK insisting VAT is paid in the UK which makes distribution complex.
Nice of them to add more complexity to the **** show of ordering.
