Good luck. I doubt if they will lower the price for you. I would call, but I'm pretty sure your haggling is going to fall on deaf ears.
Maybe if you were buying 25 bodies at the same time would they give you a break, but I am seriously doubting that they will go for it for one body.
And honestly if they would, I doubt that any of their employees that chime in on the board will say anything on here. Ever notice how calculated and somewhat vague their answers are on warmoth policy stuff? I think they have to watch what they say on here. Think about it, if they answer you on the board that they will take offers, everybody and their brother would be offering them less than their advertised price.
