Instead of having radio buttons on the checkout page, I would prefer to have drop-down options. In my industry (travel), there may be many different products offerings depending on when the trip is booked vs. when the final payment is due. So, whenever a new month passes, I have to edit the product to match the amount of time remains between booking and final payment due date. It would also be nice if the payment options can update based on the total package price vs. the # of months left to pay (instead of having to create a new product each time)
