Used to be that the only 40 lb bags that offered Prime shipping were the cookingpellets, but now the Pitboss comp mix is like $19 and available at a lot of Walmarts as well. I feel bad since I have cooked nothing but the cookinpellet hickory for a long time, but they are now pushing $37 on Amazon. Nothing but the Pitboss going forward if the price is basically half. I have been using a combination for now since I still have a few buckets of hickory, and I am not noticing a difference in flavor yet. Maybe when they are 100%, I will notice but I doubt it. About the same in ash and pellet use so far as I can tell.
