We have a neighborhood blog in our retirement community and people constantly list stuff for free or nominal prices. I have scored some incredible finds by reacting quickly.
Last year, there was a note for a Workmate - free. I was there in 5 minutes. It was missing a couple of the plastic jaw dogs and some rubber feet. Picked those up on Amazon. I use it frequently, very handy.
I posted about the Rikon 6x48" belt sander, new in the box, for $75; which I sold for $350. Got a Stanley #605 Bedrock, a #5, a #7, a Disston 28" back saw, a Disston rip saw (1896), etc. - all in mint condition and FREE!
Gotta keep the eyes open.
