Every Amazon product page has a unique identifying number within the URL that can be used to relocate that exact product again if it is still online later.
If you copy & save the whole URL it works as expected when you paste it into a browser next time, unless that page is gone for good.
But if you just read the ID number to somebody and they type it into the search box, the product will appear as a tile surrounded by a few related product tiles and the rest unrelated. Completely outnumbered, and intentionally crafted to make it easier to buy some other product besides the exact one desired.
And that's when you already know exactly what you want.
Only if you then click on the correct one will it take you back to the exact same product page.
