I buy a lot of stuff online. What I do is check the pricing ahead of time and if the price is fair I don't even bother to haggle. If the price is high I find out if the seller is willing to deal ahead of time, before I even get in my truck. I don't tell the seller what the issues are as they most likely already know. If I am going to low ball I will be up front and say I am going to hurt you with a price and for the most part it's just a starting price.
From what I have read in this forum, you have certainly had your lumps over the past year. I don't know you but I truly hope things get better and I suspect they will as you seemvery honest and helpfull.
