I guess it makes a lot of sense to just have the regular menu prices reflect promotional pricing for Pizza Hut. In my experience, there are always coupons (especially with online ordering where the coupons are part of the ordering interface) or promos for pizza to take advantage and few people I know ever buy pizza at menu price.
This new pricing structure saves people from leafing through their coupons, and makes it easier to order pizza from Pizza Hut. It'll be interesting to see how this plays out.
