What is a Promo Code?
A ‘Promo Code’ is a type of promotion that involves the customer entering a code at the checkout in order to apply a discount or

This promotion can apply a discount (monetary or percentage) to the total order, a discount to individual products in the order or to add a free product to your order if you have met the required criteria.
Creating a Promo Code
To create a Promo Code, you will need to click on the ‘Promotions’ tab in the sidebar of the admin section. The next page will show the list of promotions that you have available to use. To create a new promotion, press the ‘Create’ button at the top of the page.

The promotion creation modal will then pop up on the screen. Now you will need to specify a brief description of the promotion (so that you can remember what it is for at a later date).
You have 3 options when it comes to the type of Promo Code you can have. No matter which option you pick, you will need to ensure ‘Automatically Apply’ is not ticked as this will apply a discount without the customer needing to enter a code in.
Total Order
A total order discount will be applied to the final value at the checkout. Because this discounts the final payment, it will included discounts of ‘Add-Ons’ and shipping options.

As you can see from the example above, I have a ‘Promo Code’ of XMAS20 with a value of 20 percent (un-ticking ‘is percent’ will change it to a £20 value) and a person needs to have a total order amount of £100 in their basket in order to use the promotion.
Finally, the promotion is set to ‘Active’, meaning that this code can now be used on the site as soon as somebody has the requirements (£100 value or more in their basket) and have used the code (‘XMAS20’).
Per Product
‘Per Product’ allows you to specify individual products that the promotion can be used on. If a customer has added 3 products to their basket, but the Promo Code can only be used on two, only those two will have a discount applied to them.

When clicking on the categories field, all current categories will appear, allowing you to add entire categories (all of the products within them) that you would like this discount to be applied to.
You can also add individual products by simply clicking in the products field and selecting which you would like to add.
