Update: Wow, demand is exceededing all expectations this spring! I am nearly sold out right now (April 11, 2014). The next batch will be ready near the end of the month. A few more liter bottles are available, first come, first serve... sorry about any inconvenience and be sure to check back in at the end of April.
If you don't want to go through the process of activating the effective microorganisms, you can buy it already activated. Not only is it less expensive, but many of the microbes have recently been awakened from dormancy, so it is of equal or maybe even better quality for application purposes.
