I looked at my most recent receipt for something more realistic: A $12 (in store) pizza was listed on doordash at $14.25 and I paid $17.30 in app with the Chase CSP discount. I guess not everyone has the card, but IMO it’s financially irresponsible not to.
Note that this restaurant is a 20 minute drive each way. Even if I worked minimum wage ($15/hr in CA) it would have cost me a lot more ($10 time + $5 gas!) to pick it up myself.
