The Savannah bananas do that for their tickets. You enter a free lottery to buy tickets then pay the same price regardless of when you buy them in that window if you're chosen. I don't think there's much scalping that happens with their tickets, so it must work.
I went through the multi-step process for the bananas last year. It failed to validate me during the purchase window. Their support never responded to me (it's been 9 months now).
It was a stupid flow that sent me from email to computer to phone and had one-time links that didn't transfer between devices.
I have no interest in going through this much effort to go to an event.
