Still sitting on nine bags (I think) from the freak sale HD had about two months ago I'm good until the next really good one comes around. I had steeled myself for going though a lot more since I got the 18" WSM but, happily, it's far more miserly than my brothers 22". All gas equipment should be good until the Fourth of July unless I go nuts or it gets cold on the patio!
Since I set up an elevated dedicated spot for charcoal, rotating stock as I go, it's pretty convenient. Just moved almost all of the grilling apparatus to one side of the garage, above the coal stockpile. Rotisserie still on the other side but, it has a fairly calculated hanger so, until I decide to move that, its fine where it is.
