Read the primary article or dive into the live Hacker News thread when you're ready.
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.
When two rocks are ordered, several rocks arrive, some with no ID numbers, others with IDs that match previously issued rocks?
Sequential assignment follows strict order of payment completion only. No race conditions, no held inventory, no time windows. You either complete the transaction and receive the next sequential number, or you don't.
The constraint is designed to eliminate the entire apparatus of purchase optimization, including queue management systems.

Small suggestion - work on the semantic structure and SEO.
It's all H1 Tags as far as the eye can see!
Err, tumble money. Err, that's a good internet gag.
Next up pumice.rocks , limestone.rocks, basalt.rocks?
Quick question... Have you considered letting customers come mine their own rocks?
Do you have a low salt version?
Is there an option for pasteurized or raw?
What about sustainable practices?
What about concerns related to gravitational change from such operations?
Is there a recycling program in place?
Do they come with an MSDS and waste disposal instructions?
What about a warranty? Isn’t that required by federal law?
