My promotional code doesn't work

If your promotional code doesn't work, we recommend that you read the terms and conditions of use of the promotional code. 
We advise you to do so : 

• Make sure the code has not expired.
• Check the type of product mentioned in the offer.  It is possible that the type of product you have chosen doesn't match the offer.
• To check the amount of your cart.  Some promotional codes are sometimes programmed for a certain amount (minimum or maximum).

• To verify that you are not trying to apply an offer valid only for the first order when you have already ordered at Proteclight.
