I've been volunteering with Habitat For Humanity for the past 5 years. Our tools are homeowner quality at best and starting to wear out and and even become unsafe in some cases. I've called and/or emailed many of the big name tool manufacturers (Festool, Ridgid, Dewalt, Makita, etc) and generally found that they are most interested in providing tools gratis to entertainers and athletes.
Has anyone had any luck getting power tools donated or sold at a discount for a non-profit?
