Four things for me stick out in the under $100:

Like many people here, a no-name double edged metal safety razor: I think I got this for around $25 or so with a set of 100 blades and 3 soaps; compared with disposable razors, this has been amazing - a better shave, a nice experience to it and so cheap. it took me about 2 years just to get through the "free" box of blades for it.

Secondly a set of silicon coated spatulas for cooking. These have saved me so much food waste and have made cooking for 2 a lot easier.

Thirdly, few magnetic digital timers I've stuck to the fridge. I've found these brilliant when cooking, it makes it much easier to track when doing several dishes. I start one when I begin cooking as an "overall" time that gives me a reference and then I've two others that I'll use as needed when doing something specific during the overall meal cooking. It's made it much easier to keep everything on track.

And finally a VESA mount bracket for a cheap standing desk I have. I'm not sure what took me so long but having a mount for the monitor instead of it being on the desk completely changed the space available and made it so much more useful. I have a very small workspace so that was a driving factor.
