I happened to stop by what is left of the Sporting Goods section of my Wally World the other day and discovered their muzzleloader stuff on clearance. Two weeks before Iowa's late muzzleloader season even starts. I have a Traditions NitroFire and worry about future supply issues of Firestick. Whelp...they had plenty (albeit 100gr) at $16/package of 10. They had .50 cal sabot bullets half off too. Powder pellets, accessories, cleaning, even muzzleloader rifles...all on sale.

YMMV on stores, some have no muzzleloader stuff, some have more than others.
