Depends on the task I guess.

You could pay 100+ for a plumber to snake a drain or just buy a snake yourself and do it for <50 in parts and the next time it's free.

Perhaps for some tasks you buy so many tools it's the same price but the second you need to use them again it's a steep discount. Or you could ask a neighbor.

the tools are durable and will last a very long time unless you're buying poorly made items and treating them poorly. you can save a few hundred dollars by buying a 15 dollar capacitor off amazon and a 11 in one multi purpose screw driver to fix your ac unit that doesn't startup. (very common fix for a very common issue) all you need is knowledge and a few bucks in parts and tools.
