So with a little testing...
I've come to realize that creating a 0% coupon doesn't trigger the coupon code on checkout. Bummer!! Wish you'd consider allowing that in the code for tracking. That's all that's required to do what I am trying to use the coupon code system for.
Beyond that, I can create a 00.01% coupon which will trigger the coupon at checkout and provides me the information on which coupon is being used. I don't think the loss of a penny is going to break me. Before I set up a sandbox in Paypal to trigger a sale and test, can you tell me whether the sales detail after the purchase will have the associated coupon information in the record? Will I be able to tell after the sale that the product was purchased on discount and which discount code was applied?
Thanks again for your help!
