We have introduced a referral system on the site: after your purchase, you will receive an email with a link (also available in your customer account), which if you share with your friends and they click on this link to place an order, they and you will receive a 10% coupon for the purchase. The more GALLMET capsules you order, the more 10% coupons you will receive! The system checks for possible fraudulent use, which is automatically filtered out.
