Uber and Booking.com are out with an interesting promotion. According to the email I received, book a hotel stay with Booking.com and you’ll receive two promotion codes good for free rides up to $15 in value. Not a bad deal if you plan on booking a hotel anyway.
The offer is valid once per customer and the hotel stay must be completed by October 31, 2016. After your stay, Booking.com will send the promotion codes to you via email, with their exact value to be detailed in the email. Rides need to be completed by December 31, 2016. It is not clear to me whether this offer is targeted or not so YMMV.
