These coals are so much better than the stuff you buy from supermarkets. Branded Restaurant grade charcoal, huge chunks that burn hotter and longer than the small charcoal chips from supermarkets. £17.94 with delivery or free collection from stores, these Big K 12kg bags usually cost around £17 per bag before postage and as they last longer you save more money than buying cheaper charcoal from supermarkets. I usually get 3 cooks from a lighted set of charcoal. If you have never tried Restaurant Grade charcoal try these as the results are so much better.
