- A good quality belt. A cheap belt may last a year or two while a good one lasts decades but doesn’t cost 10x as much.
- Any sort of micro-mobility device (bikes, scooters, etc. or even costlier electric versions of these) that replaces a regular commute has good ROI over driving or even public transit (unless you’re lucky enough to live in a city where it’s free).
- A big sack of rice. It’s kind of insane how many meals you can get out of one of those.
If it replaces a car it’s cheap. Even replacing transit passes will save you money over some years.
I would pick up a used ebike. I bought two cube ebikes for 800€ each and they were as good as new.
My wife got me a handmade leather belt shortly after we started dating 10 years ago. I have worn it daily and its still in great shape. About two years ago I finally had to start using the next tighter hole as it has stretched, but theres definitely another 10 years of life still in it
