They must have changed the definition of "Free" when I wasn't looking

From the customer:

"Last month, I placed a delivery order from my local Papa John's which took over an hour to arrive. About a week later I received a coupon in the mail for a FREE cheese pizza.

I went to the website to redeem the coupon and found that a free cheese pizza is actually $1.49! I did NOT add anything to the pizza or change the size."
