That's actually kinda hard, no?

Say the server has a counter. When you load the page, it's at 57, so it displays that you would be ordering #57. While you're looking at this, someone else loads the page - what number do you show them? If you show 57, then whoever orders first gets it and the other person gets a message "Sorry, not available. Want 58 instead?" but the same thing could then happen to them with #58, too – "Sorry, not available. Want 59 instead?"

So maybe instead you show the 2nd person counter+1, i.e. 58. And you show the 3rd person counter+2, i.e. 59. But what if #59 purchases but 57 and 58 don't? What do you show the NEXT person, 57 or 60?

I'm not saying it's intractable but it merits thought.

Heads up: I purchased the first seven already.

Physical version, no blockchain needed.

I was going to make a joke about NFTs but it seems like reality beat me to it.

Feral (judging by the one in the photo).

Same kind as the Pet Rock, but worse because it's 2025.

I agree - even adjusting for inflation the original Pet Rock [1] wouldn't have cost more than about $25. /s

$49.99

It's funny you ask, I had this exact idea back during the NFT craze. I have an unlimited supply of rocks thanks to the creek in my back yard. Well not unlimited, but there are more rocks back there than people willing to buy them as a joke.

What are you, some kind of quarry robber?

One order == one rock
