Upgrading barely-satisfactory household goods to better versions. Many such goods are bequeathed or obtained when the user can't afford better, and never replaced once they're in a position to do so.
Example #1: laundry apparatus. When I was younger and poorer I bought the cheapest laundry basket and airer I could get. They weren't very good, but I laboured with them for over a decade because they were satisfactory. A replacement set in my 30s cost me less than I would even notice spending, and vastly improved my laundry workflow and throughput.
Example #2: kitchen knives. It's alarming to me how many people think a bread knife and one other miscellaneous sharp knife constitutes a fully-equipped kitchen. If you spend any appreciable amount of time preparing food, and you only own one straight-edged kitchen knife you don't know the name of, you're almost certainly making life harder for yourself. Buy an inexpensive 5-piece block set and experiment with each type of knife on different foodstuffs.
Honestly, most kitchens do not need more than 4 knives. I own and use more, but I cook a lot, and have very good knife skills. I can do almost anything I need with a single large knife (ideally a santoku, but a chef's knife or chinese cleaver would do ok as well). One serrated knife for bread.
The most important thing is that whatever knife you use is good enough to hold an edge, and kept sharp. Have your knives professionally sharpened at least once a year (or learn how to do it yourself) and use a steel to hone them once a week or before/after any h...
What can I purchase with $100 that will be the best thing I can buy to make my life better?
I've decided to budget some regular money to improving my life each month. I'd like to start with low hanging fruit for obvious reasons - but when I sat down to think of improvements, I found myself thinking of the same old things I'd already been planning to do anyway... and I'd like out of that rut.

Background:
This is a question I recently posed to my local Less Wrong group and we came up with a few good ideas, so I thought I'd share the discussion with the wider community and see what we can come up with. I'll add the list we came up with later on in the comments...
It'd be great to have a repository of low-hanging fruit for things that can be solved with (relatively affordable) amounts of money. I'd personally like to go through the list - look at candidates that sound like they'd be really useful to me and then make a prioritised list of what to work on first.
