On: Ask HN: I bought Voltaren at the chemist, now Google shows me ads for it. Why?

[scruple]

Well I've had it happen with toilet seats. In 40 years on this planet I've only ever needed to purchase that one. I'd imagine if I needed to get more than one that I would get them all at the same time.

There's probably a nontrivial number of people who renovate houses one bathroom at a time.

I'm sure there are. I'm also sure, having been around house flippers (my brother flipped for a while, my MIL flipped for a while) and reno (my parents, my MIL, and my wife when we were dating) a few times in my life, that they don't buy them through Amazon/online.

That's the sort of thing you buy a new one because one broke and now it shows up how tatty (worn, old, messy) the other one(s) in your house are. Or someone asks where you got it ... "oh, I can't remember but Google ads showed me the same one of available at $diy_store", or whatever.

Its a math mistake on Amazons part.

They’ve conflated “most purchases of a toilet seat are made by someone who buys another” and “most people who buy one toilet seat buy a second”.

There’s a small, but high volume group of toilet seat purchases — eg, office buildings or apartment maintenance.
