Care Of Vitamins is running a promotion on Sweatcoin right now. You can redeem a code today for 5 coins. Not sure how much you get upon signing up, but if you refer someone, you get 5 coins, so it's likely a new user will also get 5 coins.
This code can be applied to your first month's shipment. You can add all of their vitamins to your cart. Once code is applied, it will be $8 only for shipping.

Note: Care of Vitamins' website had some issues processing payment on their mobile site. I tried two different browsers and it didn't work. If you're on a computer, place an order on their desktop site.
