Both new and existing Uber riders can get $15 off their next Uber ride by booking directly through Google Maps. Once you’ve selected your destination, a pop-up icon will appear with the $15 discount offer. From there, you can select which type of Uber ride you want to take — UberPool, UberX, UberBlack or anything else. Note that your Google Maps and Uber accounts must be linked in order to take advantage.@thepointsguy
