Out west here Walmart just started carrying a small supply of chunks this season. I have a local weber dealer that has chunks in stock but I've looked into smokinlicious and that's a good deal for chunks, just haven't gotten around to trying them yet. CT, HD and the like out here aren't carrying chunks yet.
