My state charges Zero for duck hunting, just a small game license and a federal mig. waterfowl stamp $25. Some stAte let you order your fed stamp through them and charge a surcharge for the service but you can get it through the PO for.the standard fee. Most states I hunted in have their own state stamp in addition to the federal stamp. What they charge for the stAte stamp is up to them
Oh, I should have specified those prices were for the federal stamp.
I can't imagine why anyone in Colorado would pay 31 bucks, when the post office charges 25.
