Terms & conditions

One code per order. A code doesn’t combine with a points reward. The minimum order counts the products after pack, lab box and set prices, bacteriostatic water included; shipping doesn’t count. Codes also work on pack, lab box and set prices. Together, discounts never take a product below 60 % of its list price; the cart then shows “Best price” on that product. Bacteriostatic water is never discounted. “Once per customer” is checked against the shop account and the billing email. A first-order code is for a customer with no earlier order under the same account, email address, phone number or billing address. Delivery to pickup points and parcel lockers in 24 EU countries (not Cyprus, Malta or Romania). Codes have no cash value. The full conditions are in the Terms of sale on nexoresearch.shop. Expires May 3, 2027.
