It looks like every now and then there seem to be issues finding or selecting the right place to add an active promo/ discount code at checkout.

Below we have a step by step on how you can introduce your promo/ discount code and see if it is valid. And if so, to make sure you are getting the best price for the product you want.

After you add your product to shopping cart, as you're starting the checkout process you'll have this image on your screen.

All you have to do is click on promo/ gift certificate (we have circled this option for easier access) and a box will appear where to add promo/ discount code.

Add your promo/ discount code and click APPLY.

You'll see then that the promo code was valid and applied to your cart, as below.
