Here's a workaround.
Create two versions of your product fields with different pricing.
Create a text field called "coupon code".
Change the logic of your product fields to
"hide this field if any of the following match: coupon code is XXX"
"show this field if any of the following match: coupon code is XXX"
Right now I'm using this workaround to allow for a free product. If you enter the correct coupon code it hides the product and shows a dropdown menu instead that looks the same. The form will post and you will not get forwarded to Paypal.
Gravity Forms has a lot of possibilities if you take the time to think your workflow through.
