Heck, back in the day for me it was for Breakfast and Lunch.
For the past few months, Papa John’s has been running a nationwide TV ad for an 18” Pepperoni Pizza for $12 with one dollar going to charity. While the pizza is not the level quality I prefer, that’s an outstanding deal for those with lots of mouths to feed, so I imagine that has something to do with increased sales.
As for pizza in general, it’s quick, tasty, and comforting. No surprise it’s doing well during this pandemic.
