Where can I see the amount of discount from my discount codes

Hello forum!

I wanted to buy an item, so i went to see if I have any discount codes on my account.
When I went to https://www.warmane.com/account/history -> Promotions .
I saw that I have three discount codes. Where can I see the amount that it discounts, so that I can use the best one.

Thanks in advance.

You can't see the amount til you try to use the code. But as far as I know, you can enter the code in the popup and apply it to check what discount it would give without completing the purchase.
