Have your heard of Puritan's Pride? This is an online store where I buy all of my supplements, vitamins, essential oils and herbs. Once you visit the website you can sign up and you will get coupons and offers in your email. They send offers for 10, 20 or even 30 % off and free shipping. The best thing they do is their buy one get two free sales. They do this at leat 3-4 times a year. I usually bulk buy with a few friends or family to save the most. Here's an example: A small flask of lavender oil is about 23 dollars from DoTera. With the b1/g2 discount, I buy a 10ml lavender oil from Puritan's pride for 3.99 ! This is quality 100% Pure food grade essential oil. The quality is very good and they usually ship in about a week. I just wanted to pass on this info. Happy shopping!
