The price in your pic is the MSRP and most dealers go by it when displaying their inventory. They have room to move, but usually won't unless you are buying a large purchase at one time. It's all right on Stihl's site to read regarding the pricing. While they can vary in price around the country, it's more dependant on the regional distributor pricing than the dealership itself.
All of them at every dealer I've been to in Mich (and that is actually quite a few spread out across a 100 mile radius) is the price shown in your pic.
