Every month Young Living selects products to give away for free to those who spend a certain amount in PV (product value) that month. Those who are also enrolled in Essential Rewards (ER) will get additional promotions. The qualifying tiers are: 100PV ER bonus, 190PV, 250 PV, 300PV, 400PV.
Why it's Important to Understand PV Promotions:
If you were to place an order this month that was 180PV you'd ONLY get the products you ordered. But if you knew the promotional tier was at 190PV you may have wanted to add additional product to bump you to the next tier to qualify you for free goodies! Say you added Lemon Vitality oil to your order for only $11.50 (PV). Now your order is at 191.50PV and you are qualified for the 190PV Promotional tier and will get free products!
