This is variable.  It depends upon how many energy sessions are required.  To date, we have used the basic rule of thumb of $25 CDN per month (plus tax) for once a day service.  If a person required 3 times per day then 3 * $25 = $75 month.  This is the retail price and prices can be modified to suit your needs.
Note:  The purpose of these price points is to get it out there, get these systems being used more and more so we can all assist more people and be compensated in return. The power of technology:) This is VERY VERY inexpensive.  Less than $1 per energy session. Sessions will generally run between 100-200 minute per service per day.
