A lot of times if you know what brand and model you want, you can get a better price at a place that doesn't specialize in knives. Lighthound and Ambient Weather come to mind immediately.
The Last Confederate told us about the deal on a Sambar stag Buck 112 at Ambient Weather last year and I jumped on it and a bunch of other Buck knives at a great discount.
As far as knife stores, Bladematrix doesn't get mentioned often. They don't have much in the way of particulars but if you know what you want, just find that model and order it. If you order the wrong knife, that's on you. The pictures don't always match up but you will always get model you order.
And don't forget Budk. You can look at all the goofy stuff there or you can do a search on the exact item you want.
