It seems that Kingsford realizes there is a set of people who may buy 200-400 pounds of charcoal at once and that this adds up to a sizeable customer base. This set of folks probably barbecue a lot more often than the average backyard griller, who might go through a bag or two of charcoal all summer. Of course, I'm talking about the low and slow cookers who visit this and other sites on the web.
It would be interesting to see the sales statistics related to sales of high temperature grillers compared to low and slowers (smokers). I would venture to guess that the average low and slow bbq'er uses 5 to 10 times the volume of fuel that the weekend backyard griller does in an average year.
Due to Chris's diligence, I guess I'll keep the bags of new K I bought and give it a try. Thanks Chris for your hard work.
