Rocks in BGE charcoal

I found the most rocks by far in Cowboy lump.  I think it is the top dog in the national lump market; I can get it at Home Depot, Lowes, my local grocery stores, Ace Hardware, etc.

I have had good luck with bags of both BGE and Royal Oak. As was said, Royal Oak is who makes BGE's lump, as well as for a lot of other "House Brand" lump.  The best price price from an RO "house brand" lump was at Wegman's (a high end grocery store in the VA-NY-MA region) in MD. I have read multiple places that RO also makes lump for Krogers and Publix.  It is possible (even likely) that some of the house brands may change their supplier's from time to time, and that a house brand in one region may not supply that store in a different region.

I find something in all brands of lump.
