In the city near me, Tucson, there is a non-profit computer recycling business (businesses can write off their old computers as tax deductible donations). They get a lot of computers in there, almost all desktops though.
Next time you stop by their warehouse can you do me a favor. Take a pen and paper with you, note down the prices and types of laptops they have. Maybe we can work something out. I've been selling used laptops like crazy here.
Depends on what kind of shape they are in. Some are given to me. I'll buy a bunch for $30 or $40 each, sometimes $100 or $150 and fix them up, add memory and reload a new OS and sell them for $150 or $300 depending on what kind they are. I look for laptops that will resell high with a little bit of work.
