App occasionally tries to add double quantities and you have to be careful to check Everytime it doesn't sneak in 3 pizzas instead of one at the very end of checkout. Glitchy where glitches should be considered theft or criminal activity. Update: App now offers contradictory requirements for their promotional offering 3$ rebate code, says to be used same week, also says must be used on the following week. Neither worked. Scam! It is only 3$ but you should be sued.
