Simple.  You ask for it.  Forward a copy of your receipt to info@hypnosistherapy.ca within 30 days of your purchase with the subject refund, and I will process it within 1 business day.  Please allow several days for it show up on your statement unless you paid with a paypal balance in which case your refund will be instantly processed.  We will be adding direct credit card payments on our site in the near future as we have developed a PCI compliant site.  We are just trying to find a merchant that fits best with our e-commerce solution.
