Why are Little Caesar's cheese pizzas the same price as its pepperoni pizzas?

It seems like the pepperoni ones should be more expensive, given that the pepperoni pizzas are just cheese pizzas with pepperonis added to them.

Additionally, the pricing scheme leaves them open to arbitrage. Someone could buy pepperoni pizzas and then sell the pizzas and pepperonis separately. As long as the pepperonis sell for a positive value, this is guaranteed profit.

There are a number of possible reasons. It might be for consistent corporate branding--they want "$5 Hot n Ready" to be right no matter what pizza you buy. You can imagine customers are annoyed if they arrive only to find out every pizza *except* cheese costs more than that.

Another (more likely) explanation is that their pizzas are loss leaders. They could break even or even lose a little bit of money on every pizza but make it all back plus more on extras like soda and sides.

As for arbitrage:

1. No one wants to buy used Little Caesar's pepperoni

2. Even if they did, it's only arbitrage if the price of pepperoni > opportunity cost of removing it from a pizza. You probably make more per hour working at a Little Caesar's than you do reselling their pepperoni.
