What I was thinking, was having for like fundraisers, basically, just have your prices set, what ever you get, like say you get 50 computer towers, 40 lbs of cellphones, 50 lbs of wire, 20 lbs of motherboards and etc. I was thinking instead of going through the hassle of giving the church/school a percentage, you just flat out, buy it like you would a computer shop or what not. That would be the easiest I think for a E-waste fundraiser. Pay them up front, makes them happy, and they don't have to wait on their money.
