Where I live kero is not cheap atall.Around 20 bucks a container.
It's very cheap if you know where to buy it!
Just drop over to your local small to medium-sized airport. (NOT the big sprawling one) and ask one of the FBO fuel guys if you can buy 5 gallons of Jet-A (essentially the same stuff) . Most of them are very good at this as long as you bring a container and funnel if needed.

Depends on where you go. The huge airports will be the ones charging ridiculous prices ($6-8 per gallon) and most of them will not want to mess with small amounts going into a small container.........
A great many of smaller airport fuelers will sell Jet A for around the same price as MOGAS on the west coast. $3-4 gallon
(
Just find all your airports using http://www.airnav.com/fuel/local.html )
Most smaller airport FBO fuel operators are willing to sell Jet fuel in 5 gallon amounts. You do have to bring your own container.
You also need to either bring a container that has a "wide-mouth" opening (like a "Jeep" can etc or a big funnel because a Jet fuel nozzle is much larger than a regular AVGAS or even MOGAS (autogas) nozzle so you can't put it in a piston engine airplane. (piston engine airplanes experience catastrophic engine failure when fueled with kerosene!)
