Personally I use two brands of essential oils. I first tried Plant Therapy after researching quality, cost, and customer service.
Please read all instructions carefully. The coupon code is: OCT25 and you apply it during check out. This coupon code can only be used once per household and only one coupon per order. This sale is for their pre-diluted roll-ons ONLY at www.planttherapy.com. Cannot be used with any other discount or offer. The couplon expires Oct. 25th (2014) at 11:59 pm CST.
These are the roll-ons that I bought.
