I started a Tool Swapper Instagram where you can buy, sell, trade. You can direct message me, or use the hashtag #tool_swapper to get your stuff posted. Give me a follow @tool_swapper for some good deals, and send me your stuff to get posted!
I gave you a follow. Hopefully it grows into a good size community.
Sounds like a cool idea. I have socket sets and maybe a Starrett mic that I wanted to swap. I'll have to join Instagram
