What’s your top BIFL purchase, that might not in itself has been all to frugal, but long term, will be?
After having 5-6 different office chairs over the last 10 years, none of which I liked. I went and bought a Herman Miller Aeron chair. It’s ridiculously expensive, but I’m so pleased with it and hope to keep it for well over 15-20 years. If that actually succeed, I will have spent less money one chairs than if I hadn’t bought it.
What similar items (cheap or expensive) do you feel the same about?
I'm definitely "that guy", but chairs are hard to BIFL, as your body's needs changes. Kinda like asking for a BIFL mattress. You can do it, but not recommended.
