  • according to estimated consumer surplus per dollar spent

  • according to my low-effort estimating, in the first few days of Oct

  • purchased after the beginning of this market

  • from time of purchase over the rest of the future, attempting to account for flow-through effects (e.g. if I buy a whiteboard and then I do some great thinking using it that I reckon I wouldn't have done otherwise, then I'd sum in the value of that thinking)..

  • except not counting effects via other Amazon purchases e.g. if I hate a product however it causes me to realize that I should purchase the same in a different flavor, the consequences of that future purchase do not accrue to the first, unsuccessful attempt. If purchasing product A causes me to expect to purchase a stream of product A forever, the consumer surplus from future purchases doesn't all accrue to the first purchase.

Actually just hadn't substantially tried electric toothbrush before, so that got bonus value without the timer aspect.

@KatjaGrace We're now definitely past the "first few days of Oct" on this one.

Are there any particular kinds of products you'd like recommendations for?

@Joshua interested in anything someone loves, but best bets are probably things that make life easier or smoother for a person who struggles at the basics of life while being pretty busy with the non-basics, has ADHD and at least much in common with autistic people, sleeps badly, is often in physical pain, likes food convenience but wishes for more e.g. home-cooked food, cares about aesthetics, moves around a lot, and spends money freely. Recently pleased by a keychain device that stops bug bites itching. Long term fave non-obvious purchase was timer caps for pill bottles, so you can automatically see when you last took what.

@Austin this https://www.amazon.com/gp/product/B0B5R1FFRG/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

So far I have tried it about once on about ten mosquito bites I got yesterday. I think they became much less itchy than usual (e.g. it was not a big problem and didn't keep me from sleeping) but not all zero itchy. Glancing at a paper on this mechanism, I think it substantially helps with about 80% of bites.

It works by applying heat to the bite, which feels like you are being burned, so I could imagine a person preferring bites to this. I'm assuming it isn't actually burning but too early to say.

@KatjaGrace I got the mosquito bite tool recommended, it's a fun thing to play with and demo on friends! Kind of looking forward to getting bitten now haha
