Good Will/Salvation Army?

I have just such an arrangement with a local establishment. The big name guys like Salvation Army & Goodwill would be great whale to land with such a deal, but lots harder to reel in since you'd be hard pressed to actually meet the person who has the authority to make such a deal.

The local place, I had an in... my mother-in-law used to deliver meals-on-wheels, which is run out of the county food pantry, which is supported in part by this resale shop.

Without an in, your best approach would probably be to offer to help them reduce their garbage stream, and dumpster bill, by taking those bulky broken electronics off their hands. Of course, that means YOU have to find a place to dump all that stuff, but such is the life, right?
