What a bummer that your discount code isn't working! This is certainly no reason to panic. When you want to use a discount code, it's important that the products in your shopping cart and/or the order value meet certain conditions.
The code shows as 'applied succesfully' but I don't see any discount or a free product added.
I receive the message 'the coupon code entered is not valid'.
I receive the message 'the entered discount code has already been used'.
How do I know if I will receive a free product (with a specific promotion)?
If you are using a promotion that offers a free product, the product will appear in your shopping cart after adding the code. If the product is not displayed, you do not meet the promotion's terms or the product is out of stock.
The discount in the shopping cart doesn't match with the discount code.
Check if all products are eligible for the promotion; some products may be excluded.
All our terms and conditions for active promotions are visible on the home page banner and product pages.
