What can I do if I have a discount code and it doesn't work?
To apply the discount code you must be registered at www.difusion.com/tienda and be logged in at the time of purchase.
Remember that the account in the Difusion online store is independent from the one you already have registered on the Campus Difusion platform.
If you are not yet registered on the Difusión website, you can do so by clicking on this link.
Check that the code's validity date has not expired. Enter the code in the shopping cart and click the "Añadir" (Add) button.
If the error persists, please contact our customer service by filling this form.
