There are absolutely NO minimum monthly purchase requirements. To remain a wholesale member, you have to make $50 worth of purchases per year to keep your membership. But if there’s a year that you don’t make a $50 purchase, you can reinstate your wholesale membership discount by just placing a $50 order.
If you do find yourself making regular purchases each month, then Young Living has a rewards program (called Essential Rewards) where you can make a nice percentage back in product credit each month on all of your purchases. So that’s a neat program to join if you find that you *want* to purchase regularly (but it’s not a requirement for being a wholesale member).
