Bass Pro has similar prices, however given their current political position I'd recommend buying from Cabelas.
I keep a fairly close watch on the prices of C&B, which are a passion of mine, and short of locating a dealer that will give you a break on suggested retail prices Cabelas is your best bet. I've had several "dealer" catalogs over the years for the various importers of black powder guns and the mark up is even greater on them than smokeless firearms.
Eventhough you didn't ask I'll also mention as a sdie note that I'd recommend the steel frame models. In my personal opinion the savings from purchasing the brass frames is not worth the difference.
We live in a time in which attitudes and deeds once respected as courageous and honorable are now scorned as being antiquated and subversive.
