Applying a Discount Code
If you have a discount code for Promote Labs products listed at http://PromoteLabs.com you claim it on the Checkout Page.
So add to cart all the items you wish to purchase with the discount.
Scroll down to just above the payment options and click on the green text "Click to enter it here"
This will open a box where you can type or paste in your discount code. Once you click "Apply", if the code is valid for your purchases, you will see it has been applied by looking just above the TOTAL information. Please note that the box where you typed the code is cleared (ready for another discount, if any!)
