material prices

when gas hit $4.00 per gallon 2 years ago and it cost $120.00 a barrel, material costs shot thru the roof(excuse the pun). Then gas dropped back to 70-75 per barrel for over a year. But they didn't reduce our material costs. Now gas is going up agin and their talking about more material increases. I don't understand why we didn't get a discount when oil dropped by 45%. I think the suppliers and mfger's are taking advantage of us, not just the oil companies.

So you think fair should have something to do with it? Bend over and "asume" the position! Wars cost a lot of money to run.

Ive been saying that all along,you have only 6 major shingle manufactures now,why? Because like the oil companys its easier to manipulate the market and control pricing.
