I'll pass. Kingsford on my big 'ol 24" Horizon offset smoker falls through the charcoal grate soon after turning white. I've switched back to my favorite charcoal (mixed with sticks of course) which is Sam's choice charcoal. Very large coals and lasts way longer than Kingsford.
Which brings me to a point to ponder....how come you can buy Sam's Choice charcoal at Walmart, but you can't buy it at Sam's Club ????
Anyway, I think Kingsford is full of crap in that they've reduced the amount of charcoal per bag and tell you that it actually lasts longer than the heavier charcoal they used to supply a few years ago. Wasn't the double bag like 22 pounds per bag and now it's something like 18 pounds per ?? Sam's Choice is 18 lbs per but like I said, the coals are much bigger and produce a longer burn, at least in my experience.
Feel free to correct me if I'm wrong here, just my personal experience.
