Just in case you may be interested, Kingsford Charcoal is on sale at Walmart. $7.98 will buy you 30 lbs of Charcoal. They also have Royal Oak Natural Lump Charcoal in 10 lb. bags in the $7.00 range.
Home depot is selling Kingsford for $12.98 for 40 lbs. With my military discount, I walked out with 40 lbs. for $12.55.
Just in case you may need to stock up.
