I was quoted $0.69/ft for #8 AWG yesterday, and found a 500' roll of it at a box store for $134. Needless to say, I bought it...

As far as bidding the job, I'd simply include a caveat / disclaimer about "due to the fluctuations in the copper and steel commodity markets, these prices are effective the date of bid only..."
