My wife laughed at your shopping cart. She has already chided me for the many bags of pellets I have. I got several hundred pounds of pellets that the guy who sold me his Rec Tec had bought. I have yet to use all of that up not to mention the ones I have bought.
If any of our Lowes would have had that price, though, I would at least have grabbed 4 or more bags of the Grill Master Blend. All the Lowes around us show $16.98 a bag. For that I will keep using up my inventory including untried blends from Lumberjack and Bear Mountain. Maybe one of those will turn out to be as good as Grill Master. I did note that one of the bags listed the same blend of ingredients that Weber uses in its Grill Master.
