For some select users, they have been targeted by this new promotion of a free month of Uber Eats Pass. You will need to open the mobile app on your phone to see if you were targeted by this offer. Here are some details about the pass: "Eats Pass is an Uber Eats monthly subscription for $9.99/month. Eats Pass subscribers get $0 delivery and 5% off orders over $15. These benefits apply to all restaurants on Uber Eats in the subscriber's city."
If you are targeted by American Express with this AMEX Offer in your account, then you are eligible for this discount! You won't need an Uber Eats code to activate it. Just activate it through your American Express account.
UPDATE: The discount is for select restaurants only now. To help local, independent restaurants, Uber Eats is waiving all delivery fees! An Uber Eats coupon or promotion code is not needed to get this discount. Just order your food like normal and see the discount apply automatically at checkout. This offer may not last long!
At select restaurants, you can buy 1 entree item, and get another 1 for free, and this doesn't require an Uber Eats promo code. Just look for the ribbon to identify which restaurants are participating in this promotional offer.
