Although I agree with this. Websites like Silencer shop, due to their inventory and size, are able to offer things that the Class III dealer down the street isn't. Many manufacturers offer discounts through SS that aren't offered at other places. The main one being the tax stamp paid.Keep in mind that a suppressor has many hands in the pie. The manufacturer gets a piece, the selling dealer, the transfering dealer, and the price of the stamp.
If you want your local gun dealer to get a part of that pie, deal through them and not directly through the silencer shop. You can find a list of dealers by logging on the the silencer shop and finding their partners around the state.
Your transfer dealer can also be your person that you buy it through so they get a double shot of the money your spending.
