Roger,
Steel prices have gone up as well. I just ordered an 84" construction attachments extreme duty extended tooth bar to go over my bolt on cutting edge. The dealer quoted me $590 he called and placed the order with CA today. they said that 2013 prices have gone up 4% due to steel cost. So new price is $613 he called to make sure i still wanted it. I don't think they care if they had it last year they just look at book prices and then mark it down to their normal discount %
