Just realizing my last bag of Kingsford charcoal I am using up is a 20 lb. bag, and that Lowes and Walmart are selling 18 and 16 lb. bags. Pretty much the same money I recall paying for the 20 lb. bags (usually 2-bag deal) a few years back. Or is it that the 20 lb. bags are still available and sometimes places have it and sometimes they have the smaller bags?
