The deal is offered across all American Express cards which has to be added to the card from the Offers page on the website or mobile app.
The fine print states it is a one time add-able/redeemable offer valid until 3/31/2019.
Redemption possibilities include taxi rides equal to or greater than $15 or take-out food worth $15 or more including delivery charges. In both cases you effectively pay only $5 or more.
Basic T&Cs for the card are-
- Must use enrolled Card as payment method directly with Uber account.
- Offer valid for transactions with Uber mobile app, Uber Eats, and uber.com.
- Not valid for international rides.
- Excludes gift cards and Uber Bike transactions.
It’s basically free money for most people, either for rides or for UberEats. The offer will only provide you a credit for the cashback, and not points.
