I am the small timer working out of my garage, so I don't know how useful my input would be, but I'm going to throw it out there anyway.

I tried craigslist, ads kept getting flagged. I mainly use freecycle and word of mouth. Both have yielded me with as little as a tv and VCR to as much as a trailer load. I have one regular supplier who specializes in freon. During summer he was getting me 10-15 tvs/monitors a week, plus smaller items like VCRs,DVD players, radios, etc. If you want to post flyers, I suggest the least thought of places...you may have the community board at the gas stations and super markets, but theres also small work out clubs, and independently owned buissinesses with only one or two employees, but still have enough traffic for people to take notice of signes
