A Adidas discount code is a secret code whose operation is very similar to paper coupons: just apply it to the cart on the site https://www.adidas.co.uk/ before payment to obtain a discount in a fixed measure or in percentage. Many times these codes also allow you to get free gifts or for example free shipping. If the code doesn't work, remember to check the promotion details, as they often have specific terms (such as a minimum purchase cost) and apply only to selected products.
