First, make sure you are buying $100 worth of products or else this won't work
Add whatever domains you are trying to register, and proceed to the "checkout" page. (Be sure to READ CAREFULLY on your way there so you don't add useless products on the way)
Once you are on your checkout page, observe the "Total Price" column to make sure you only have what you intend to buy.
After that, simply look for a orange button that says "Apply Code" and in the white text box next to it, copy this into it...
Click APPLY CODE, and you will receive your discount.
