Jesus, dude. Don’t blow a fucking gasket. For hundreds of millions of DorrDash customers, this isn’t the way it works. For example, the combo meal for a burger at my local McDonalds is $10.49 in the McDonald’s app, but $12.43 in the DoorDash app BEFORE you add any of the non-hidden fees.
I’m glad that DoorDash is cheaper for you, but it doesn’t work that way for 99% of their customer base. You are an unusual exception.
