I've been in their shop once, about a year or so ago. Nice guys, know their business. The shop is out in the country about a half hour from Augusta. I did not buy anything but spent a lot of time looking and checking.
After hanging around here and other sites dealing with shotguns and giving the matter some thought my impression of them has moved somewhat. I think that they are pretty fair in their description of the guns, but I think they are a bit overpriced. Having spent a lot of time over a long period shopping the internet, I will say some of the same guns have been there for over 2 or even 3 years. Whether that's a normal event in the gun world I'll leave to others. Because I didn't buy anything, I can't comment on whether or how or to what extent they'll haggle. That said, the wall o' Foxes and Parkers is something to see.
I also think that, if you're in the market for a Savage 99 lever gun, they might have the market cornered. I have never seen so many in one place....
