GrubHub and Seamless has a promotion going on for new customers. If you sign up now, you can get a $10 discount on your first order or $15 or more.

GrubHub is similar to other delivery apps. You download GrubHub, register and then search for restaurants near you by entering your zip code. You should be able to choose almost all items that would be available in store. You can also choose between delivery or pickup. Deliveries can also be scheduled for later in the day, which is a pretty useful feature. I have used the app a few times in the past.
Tipping can be done in app, so no cash is necessary when you food is delivered.
There’s a few similar apps out there, but if you haven’t used GrubHub or Seamless yet, then it’s worth trying out, at least just for the signup offer. Place an order of $15 or more and you will receive a $10 discount.
