Update 5/7/21: THATNEWNEW $10 off any order on Postmates once you link it to Uber. Hat tip to reader Jon
Some Postmates customers are being given the option to link their UberEats accounts (option is given when opening Postmates with the latest version, but not all locations/users seem to be eligible currently). User can then use UberEats credits in the Postmates app (e.g the Platinum credit). Postmates currently has more frequent promo codes than UberEats, best resource is this reddit thread.
