Hello. I would like to display a custom message on the Thank You page if a specific product is ordered. Their license code is autogenerated and currently E-Mailed to them and placed in the order status, but showing it on the Thank You page as well would be a bit more intuitive.

I see at least two possible solutions.
1. If product X is ordered, display a custom message generated on the fly.
2. If comments were added to order status, display these as they are likely relevant.

Or perhaps there's another way. Can this be done with the notifier system?

Thanks for any help.
