Montana sets no statewide minimum purchase age in statute, so expect retailers to check your age. Approved stands and retail stores sell fireworks only during the legal sale windows — never by mail order, and never within 300 feet of a hospital or church.

South DakotaInfo
South Dakota specifies no statewide minimum purchase age in statute, and fireworks are sold by licensed retail and special-retail dealers during seasonal windows. Neighboring states sell aerials that South Dakota bans, so buying across the line may still leave them illegal to use in South Dakota.

WyomingInfo
Wyoming's fireworks statutes (W.S. 35-10-201 through 35-10-208) set no statewide minimum age to buy or use consumer fireworks. Any age condition comes from county resolutions or city ordinances, which may also prohibit sale or use outright — and a local ban makes use or possession illegal regardless of where the fireworks were purchased. Violations are a misdemeanor: fine up to $750, up to 60 days, or both.
