I've never seen this before - is this a thing? I went to buy tickets for Super Furry Animals in Cardiff, got to the stage where I could enter my card / address details etc etc. And by the time I'd done all that, the tickets were no longer available. I took no more than 2-3 minutes doing this.

I thought that once you got to the "enter your details" stage, you were allowed a few minutes to type them in.

It's no big deal (I'd still have to sort out hotel and childcare if we did go) but I'd just never seen it before.
