doTERRA offers the highest quality CPTG Certified Pure Tested Grade® essential oils without minimizing purity standards that so many doTERRA customers rely on for health benefits. In the past decade, costs associated with growing, distilling, and producing essential oils have changed. While most oils have become more expensive to produce, expanded supply on others have led to some lower prices. Please be aware that on February 1, 2019 adjustments will be made to USA and Canada prices and will be updated online. Please know that we diligently work to keep doTERRA essential oils as affordable as possible and strive to lower costs and pass savings on to customers. Online prices at https://www.doterra.com/CA/en or https://www.doterra.com/CA/fr will always be the most up to date and accurate.
