Just got an email from Uber Eats with a code for one free delivery: EATSTREAT18
As the title states, it could be targeted but worth a try if you're going to order something. I wouldn't post it if the code was unique but since it looks generic, why not give it a try. Fine print states:
"Free delivery" means there are no applicable booking fees and/or busy area fees. Must: (1) receive this email directly from Uber Eats to qualify; and (2) use this email address to log in and order to qualify. Valid through 01/28/18 at 11:59pm PT. Code may be used only once per user. Must enter EATSTREAT18 at checkout to receive discount.
Good luck. Enjoy.
