As you can see, if the customer notices the Layaway option while shopping, they can simply start the purchase off as a layaway, using the layaway code for 50% off. When the order is received, whoever is managing it sees the "layaway" in the order for the discount and knows it's a layaway. I guess she makes or has someone make the follow-up payment product for that customer

I think a pretty clever way and don't have to worry about some mod working properly (although we might be interested in such a mod). But since it's all core zencart function it seems safer.
