Each promotional code has specific rules regarding its use, such as the validity period, the minimum amount of the order, or the type of products purchased and the fact that it cannot be combined with other promotional codes.If the system does not recognize the code you inserted, ensure that the order fulfills the validity of the promotion. If the code is declined again, ensure you entered the characters correctly: often the number "zero" can be mistaken for the letter "o" or the number " one" for the letter "I."
