Hey Linda! Thanks for the reply. I'm not quite sure that I understand though. Let me tell you what my goal is and if you get a minute, let me know if it will be easy to accomplish.

For example, in our Google ads we would like to use a destination URL like "mysite.com/index.php?tracking_code=google&keyword=whatever"

Then, when they checkout, I would like to put "google" into the discount code box and then append "whatever" to another piece of data, like order notes, before it goes into the database.

So, basically, whether the customer is new or returning, I want to autofill the coupon code from the URL so that they don't have to think about what code to place in the box.

I attempted to send myself a discount code from the admin panel, but the link in the email didn't contain the discount code - I would still have to enter it by hand.

Let me know if the method that I proposed earlier seems salient, or if it could cause conflicts. Thanks again for your help!!
