We didn’t do much discounting as we did bundling specials such as 12 wings & 2 liters free with the purchase of 2 xl pizzas and get a free large cheese with 2 xl pizzas. Those specials really put us well above our normally Sunday sales.
Our special was 2 mediums with 2 toppings each for 20 bucks. Most orders were about 3 dollars off full price but we had so many orders and so many large orders, that it was well worth it.
