You can get it for $1.20 a lb, plus shipping, in10 lb blocks. A 5 gallon bucket will cook one person's food for nearly a year, when it's used in a coffee can, with 5 wicks, inside of 1/2 of a gallon can. Put some 1" rocks between the 2 cans. Poke nail holes in the bottom, sides of the outer can, in the sides, ( above the wax) in the coffee can. Fill the coffee can a bit over half full of wax. This ensemble will boil a qt of water in 5 minutes or a bit less, a gallon container of water in less than 15 minutes. So the 5 gals is a great plenty, unless you have a large family group. This is a great way to "lay low", not having to get wood for cooking, not sending up smoke during the day, or having flames showing at night. Either can be seen for many, many miles, from a high spot, tree, etc, with a riflle scope. Were I a looter, such is what I'd be looking for, and I'd be listeningfor generators, shots, chain saws.
