I recently started delivering with DoorDash to add some cushion to my budget and this week I had someone buy a single two pound bag of spaghetti noodles from Safeway.
I got laid $6.75 for the delivery after tip (DoorDash paid me $4.75 and the customer gave me a $2 tip). The noodles cost 3.84 at Safeway, and $4.18 on the app, and Safeway is a zero dollar delivery fee shopping experience.
As far as I can tell, it cost DoorDash a dollar or two for me to make that delivery, and/or the customer paid a lot more than $6.75 for the noodles for it to make sense for DoorDash to take.
