Special Offer Code on Checkout Page

[WoolforEwe]

I am just setting up Actinic Express and am wondering if I can set a field to accept special offer codes on the checkout page.

I also haven't found a way to customize customer invoices -- for example, add our returns policy.

Thank you for your help.

Anyone know of any movement on this?
