So I'm a huge idiot. Every couple of weeks I drive to Overland Park Kansas to pick up Q supplies frome Smoke n Fire (long drive and fairly expensive). Come to find out, here in smallville Sedalia Missouri, Young's Ag and Vet is a great source for rubs, sauces and other Q needs. He even had several cookers: Green Eggs, Louisiana pellet grills, etc.
So, if you are in the area or going through Sedalia on 65 highway, give them a stop. I'm all for you guys who have your mail order stores and will support you when I can, but there is something to be said about buying local.
They don't have a web site, but here's a google link with a map and such:
