The deals for any of these meal services are bullshit in my experience. There's a lot of hidden fees or minimum order amount stuff that isn't apparent until you get to the checkout, definitely not the great deal they have you believe you're getting.
We have a restaurant where I can order a $10 meal and pick it up myself. The same meal done through uber is $30. Everything has a percentage added and there's at least 3 extra "you used us" fees that get tacked on. All the menu items can have anywhere from a 20->100% markup. It's quite insane.
