Your friend uses the code at checkout When your friend gets to the checkout and spends over £100, ask them to enter the referral code. They will receive a £40 discount off their order, and you will get £40 credit added to your account. Referral Scheme Terms and Conditions This Scheme applies to referrals to new customers who complete a purchase and are assessed as eligible for treatment by our clinical team. There is only one reward for each new customer introduced. Referrals are limited to 100 within a 12 month period. Discounts and credit only apply to the product and not to shipping costs. Rewards are only valid if your referral is not someone we already know (ie a current or past customer or prospect). We reserve the right to withdraw your reward if the referred customer order is cancelled or rejected. We reserve the right to terminate this referral scheme at any time. We reserve the right to refuse access to or to terminate access to this Scheme to any individual for any reason. Referral codes are only to be used for passing directly to personal contacts. The publication of your referral code on public websites is prohibited. Unused rewards credit expires 1 year after a successful referral.
