On the NEW side of the house, let me tell you that it is a simply matter of economics. As a dealer, you MUST stock X number of dollars of manufacturer M's product. Same as X, Y, and Z's. That is a fair bit of overhead to carry. Then wages, then rent, other types of overhead. Usually the price asked is a fair price based on what the dealer is paying. When it isn't, go elsewhere. I have never haggled on any new purchase. I usually know the price from several other places first. I ask the price, if I don't like it I say thank you and leave. If it is far more than any other place I have checked, i will let the seller know that that same thing is available at BBB outfitters for $$$. Often times the seller gets upset and I have gathered valuable info...don't go back there and soon someone else will be renting that building.
I never could understand haggling. I don't do it. If I ask a price for anything, it is because I feel it is a fair price and the item is worth it. If you don't want to pay that for it go away! Shipping costs money.
However, I must agree with you on the used items comment. The posts here in the EE are often inflated beyond new! If a person hasn't done their shopping around and research, then they can get rooked. See, when I buy used, it is used. NOT new. Same as a car...buy it new, drive it off the lot and you just lost 25% of the value of the car. It is no longer a virgin. Not worth as much. Most times, I can buy the same rifle through Cabela's, shipped to my door, for the same of less cost than buying "used, never been fired" (hah!) on the EE. I don't care if it is still in the sealed box with the postman delivering it as I sign the deal. IT IS USED, better lower the price. There is a local retailer here who greatly inflates the value of his guns in his shop, he could do this becasue he was the only one around for quite some time. Unfortunately, he still sells guns to people but only once. I dropped in the other day (he sometimes gets some rare stuff on trade) to hear him lament to a customer how hard it is to sell even used stuff these days. Fewer and fewer people are buying guns today. I told him that it was actually that fewer and fewer people are buying guns from him today because there are better places nearby now to do it. He asked me to leave.
