I know it doesn't fit with the normal western hunting theme, but a local sporting goods store here in Missouri, Rogers Sporting Goods, does an annual truckload sale. Their prices are pretty tough to beat on waterfowl gear and shotgun ammo.. I'm not sure about shipping costs, but I know quite a few guys from the opposite end of the state have stuff shipped to them..

Ivory Tip, since you're gonna be a treestand hunter now, they have some smoking deals on treestands.
