To add a discount code to your account, you need to have at least one active plan.
How to add a discount code
To add a discount code, head to your account at KatKin.com/login and log in
Click ‘Manage Plans’
On your ‘My Plans’ page, scroll down to ‘discounts’
Put your discount code where it says ‘enter code here’ and click ‘add code’
If the discount code is applicable to your plan, it will be visible in the price breakdown of your box.
I applied a code successfully but it hasn’t reduced the price of my box?
Some discount codes are only valid for new customers purchasing trial boxes, and not for recurring orders.
Discount codes will also stack in your account, so if you have a larger discount saved, that code will be used first before smaller discounts.
