It was at least 6-7 minutes.
I initially added the 3070 to my basket as it was the first link I clicked. My adrenaline immediately rushed, I panic started filling in details.
Halfway through I thought to myself, why am I not getting the 3080? as that is the one I wanted. So I opened it in a new tab and was prevented from adding it to my basket as it was already full.
So I opened Firefox and pasted the URL, then I needed to prove I was a human by clicking buses and planes, and it was still available.
Then I had a problem on the payment verification screen popup not letting my click the verify button, so needed to go back and fill in payment again.
Then had to run upstairs and get my mobile to enter a passcode for payment verification.
And it was accepted.
I just checked the timings, and the verification happened at 19:37, and my order went through at 19:46.
I think the cheaper cards all went quite quickly.
