he didn’t pay for the bread bites though. OP says he’d use 20 points every time to get free bread bites. So he would pay the for the pizza but not the bread bites. he ordered both at the same time. He would get 60 points automatically because he ensured the delivery would be slow on purpose.

So if he was doing that every order, he’s making a point profit of 40 per order. Eventually he would have enough points built up to not even pay for the pizza AND bites.
