Today I had a call from a semi-professional scrapper that should serve as a cautionary tale for everyone that buys their material. She called our company looking "to get as much cash as possible for 8-10,000 lbs of motherboards." I paused for a second to wipe the drool off of my mouth and asked her what she was hoping to get for them, the response was $4.50/lb.
I'll wait a second while all of the e-scrap buyers on this forum stop laughing.
I gently asked her how much she had paid for the boards, and her response was $4.00/lb ($32k+). When I asked what she had based the pricing off of, she replied with one word: eBay. To make matters worse, these were all newer, lower yield and Chinese boards. Needless to say, I did not jump on this deal.
Even as a buyer, I never purchase large quantities of high-value material without having a locked-in price. Always get a current quote before laying out enough cash to buy a new car, and never base high volume deals off of eBay.
