A great way to restock your Starter Kit oils, ***AND*** earn points to redeem towards free (yes I said free!!) oils, is to join the Essential Rewards program. Essential Rewards is a monthly autoship program.
There is no cost to sign up and you can cancel anytime! Your monthly order must be at least 50pv (basically your order must be at least $50). You then earn product credits on your monthly order.
Months 1-6, earn 10%. Months 7-12 earn 15%. Months 13+ earn 20%. Yes, you are reading this correctly, the longer you participate in Essential Rewards, the more you earn! You also receive reduced shipping rates. Below is a great example of how to restock the Starter Kit oils (but in the larger 15ml size!) for about $50 a month. Ordering like this for 6 months will give you about $35 in ER credits to cash in for free products!
