Straight razors- bought a pack of blades years ago for change and have yet to run out
Aeropress or V60- especially with beans, after an initial investment of ~£100, you can buy the cheapest beans in bulk (freeze to last) and still make better coffee than any shop

Oh god, what's the issue with toothbrushes?
Switched to Kobo Forma when kindle got ads, love it
Replacement electric toothbrush heads run on the same scheme as disposable razors with high margins and vendor lock in. I’ve also seen vendors (Phillips) change the design to force you to buy another base station/brush.
Also you can't replace the battery. So if you electric brush is dead, you will need to replace the whole thing.
I do love my Kobo Libra 2, also allows me to just put my epubs on the thing, without the need for subscriptions. etc.
