Seems they're started this promo again as app has a pop up. Ends on Tuesday 21st 5am. This is funded by DoorDash and they also have lower margins to restaurants than UberEats. Local burger place was saying during Covid DoorDash charging 15% to him, and UberEats, Deliveroo etc all 30%+. So he preferred I used DoorDash.
Enter promo code 50JULYAU at checkout for 50% off your first DoorDash order
Capped at a maximum discount of $20 and new users only.
Works on both pickup and delivery of orders (seems also if you order >$40 from most restaurants you get free delivery as well) so if you get $40 delivered, it'll cost $20 inc delivery.
As far as I can tell, places on there still hike their prices up just as much as they do on Uber Eats, compared to what you pay in-store.
Seems like the customer is the one who misses out on that saving between uber and door dash
