Here’s a couple examples from my life:

1. Safety Razor. I get a better shave and it’s like $15 for 100 razor blades, which lasts me a couple years. Way way way better than the disposable multi-blade Gillette things, which sell 5 heads for $20.

2. Handkerchiefs. I am prone to allergies, so instead of constantly buying disposable tissues, we now have a stack of handkerchiefs that can just be used a few times and then thrown in the wash. This has also saved me loads.

What about you?
