Alapaint, I understand you point. However my suggestion would be to make every effort to be precise in your bidding especially in this economy.
There is an old story of two unsuccessful men sitting on a park bench: one said "I always bid low" the other "I always bid high."
My point is, if it is working for you then great. In the long run though becoming astute and well versed in gathering all the information that you can and bidding competitively will keep you moving forward. It takes experience and is a learning process. And we never stop learning do we. You have to know your market and obtain a good reputation.
Sharon, I will be back a little later. May I ask that you please make a list of exact questions for me and we can start by answering those, thanks.
