Is this a programming problem?
I've never even heard of a UPC Coupon Code before, I'm guessing it's this:?
In which case after a quick look I'd take a guess you can't. It seems to have a strict structure.
Is there any reason you think you could combine them? Have you seen it done elsewhere? Is there a standard for this?
Really what we do here is help with implementation based on your design and code.
Your question as it is doesn't even give us anything to try and implement so I'm not sure how much we can help.
