Best Pricing for H&R 12 gauge Tracker 2 Combo

[3screwsloose]

I was thinking of getting a H&R single shot 12 gauge slug gun I think is called the Tracker 2 and saw on their website they offer it as a combo with a muzzle loader 50 caliber barrel as well. Does anyone have any experience with these, and where would one find the best price on such a combo? Thanks, Peter H.
