I deal with mostly commercial and they choose the lowest bidder every time. If someone is cheaper the next yr. by $10, they get rid of you. This has happened to me way too many times. I wish I could get away from that cheapest bidder mentality. I was going to bid on a school system last yr. with over 60 acres of turf in the county. The man accepting the bids told me to not waste my time because the guy who had been doing it only charged $37,000/yr. for the entire system. He said that if he were crazy enough to do it that cheap, they would keep giving it to him. He said that I'd do the same if I were in his position. I can name other numerous examples but I don't have enough time.
