I have no clue about standard pricing on them as I use only loose powder but I personally would consider that a ridiculously high price. Since you use three at a time or most who use them do that would mean you're getting only 33 shots from that bottle and they are gonna cost you about 86 centers per shot just for powder alone. Add in the expensive saboted bullets folks use and you're well over a dollar per shot from a muzzle loader. To me that's outrageous.
