My experience is that there's always a hidden surcharge with DD or Uber eats. Like fries are $3 if you call it in yourself, but are $3.30 or something in an app. A couple years ago I had a $10 off $40 coupon and dash pass from my credit card. Total after fees for pickup was like $55 and just calling it in myself was $45.

Not saying it's impossible to save using them, but good luck.
