Yes, I do it all the time! Although, I do remember the first time I did it I could not find where to add/enter a gift card when checking out via the dominos iOS app, so ended up going to the website and doing it there instead.
Luckily, since then, I found where to add a gift card via the app! It’s really small and inconspicuous so it’s easy to miss! You will find it on the page where you enter your payment method. Directly above your list of saved credit/debit cards you will see (barely see) where you can add a GC.
Something else important to know is that you won’t be able to add a tip using a GC on the app or website. You will have to manually write in the tip on the slip when they deliver your order. Right now in my area, due to the pandemic, it is all contactless delivery so I don’t think they’re having anybody sign, so when I use a gift card I just give a cash tip. Hope this helps!
