Discounts can be used to create campaigns in your Tictail shop. For instance, if you wish to put certain products or your entire stock on sale, you can create a discount with the help of our Discounts feature in the smartphone apps.
To manage your discounts, go to your store settings by clicking the cogwheel in the bottom menu row and then discounts located under 'Payment'. From here (image 2), you are able to manage your discounts by either edit or create them. 
Set the details that you want and click save, you will end up back on the discounts listings page.
