Simple. They only need 9 signs per store.

Sign #1: Due to Obamacare, we now only offer 8 pizzas. If you have any comments or complaints, please call your Congressman and President Obama.

And a sign for each pizza.

Better yet, just one pizza, a red pizza, just crust and tomato sauce...

If you add $6.66 they can add some cheese in the shape of a hammer and scicle.

Only 1 sign per store: Cheese Pizza only, provide your own toppings at home.
