If you really want to save money, make sure that what you already own is organized. This reduces the amount of re-purchasing that occurs, in general. When it comes to tools, this amount increases greatly. Years ago, we had tools scattered everywhere and could not find the tool that was needed for something specific; we ended up purchasing another, using it, then finding the first one. What a waste. Eventually, my father-in-law got fed up with this lack of organization and bought us a tool box. Then, two years later, he bought us another tool box. He was so frustrated with our tool disorder, he started bringing his own tools over. Finally, we bought a tool cabinet. This has become our organizational tool. You need to figure out what works for you and go with it. We no longer find ourselves buying tools that we already have, nor do we find prior owned versions of tools we do purchase. In the past few years, we have probably saved ourselves over a thousand dollars in wasted tool purchases.
