Back in June, American Express and Uber partnered to launch a new feature in Uber’s iOS app that allows Amex cardmembers enrolled in the Membership Rewards program to choose to earn 2x points on Uber rides or to redeem their MR points for free Uber rides. More info on that program can be found here.

Today, Amex introduced a new, separate Uber offer: after syncing your card and registering for this promo, cardmembers can receive a one-time $10 statement credit after spending $10 or more online at Uber for a single ride by December 31, 2014.

To take advantage of this offer through Twitter:

1. You must first have an American Express card connected with Twitter (see sync.americanexpress.com/twitter for more details on how to connect your Card)
2. Tweet using the hashtag #AmexUber
3. Receive a response message through Twitter from @AmexOffers stating that this offer has been added to your connected Card
4. Then, use your synced card to spend at least $10 at Uber by December 31, 2014

Full terms of this promo can be found here. Note that if you are enrolled in American Express’ program with Uber, you will not earn 2x points on the portion of the fare covered by the $10 statement, nor if you select to “Use Points” in the Uber app to redeem points for a ride.

If you don’t have a Twitter account and don’t want to create one, you may also be able to find this promo through the other Amex Offer channels:

• Your AmericanExpress.com account – Log into your online account and click on the “Amex Offers For You” tab.
• Use the American Express iPhone App and visit the ‘Offers For You’ tab in the ‘Membership’ section
• Through Facebook at amex.co/facebook

UBERAMEX: $30 Off for first time Uber users
If you’re new to Uber, you can also get up to $30 off your first ride when you pay with your American Express card by signing up with promo code UBERAMEX:

• Promotion code UBERAMEX must be entered prior to taking first Uber ride
• Discount will only apply to your very first Uber ride and only if you select an American Express Card as your payment method for your ride
• Only valid in the US
• Not valid with any other offers
• Limit one discount per person
• Discount will not apply to rides using the TAXI option

Despite the terms of UBERAMEX stating that it’s not valid with any other offers, the fact that the $10 off Amex Offer is coupon-less suggests that there’s a good chance that the two offers will still stack, such that you could get $40 off your first ride if the ride costs more than $40. If someone tries this and it works, please let us know!
