Just Vitamins Discount Code Referral Scheme Recommend Us and Earn! What can be better than a fantastic loyalty reward earned by you, for helping to spread the word to your friends and family about Just Vitamins? It's very simple and straightforward to earn your reward and send your friends and family a discount: Send a referral discount code to a friend/family from your customer account. They will receive a 20% discount on their first order. Your friend/family member redeems their discount code with their first order. You will then get a £5 discount code redeemable with your next order (minimum spend £10). You get up to 5 referrals in your account - that's up to £25 of savings, plus you can request more at our discretion.
