Google has made it simpler to keep track of all available Android Pay discounts: The big G has launched a promotions page for the service, similar to the one for Chromecast. It details all the promos you can take advantage of for the current crop of Android Pay-compatible apps. For instance, the page lists Uber's offer, which gives you $10 off for your next ride, and explains that you'll have to type the code ANDROIDPAY in the ride-sharing app's promo section to claim it. On the other hand, some applications automatically apply discounts if you choose the mobile wallet as your payment option upon checking out. If you regularly use an app that's compatible with the service, you may want to check the portal every once in a while to make sure you're not missing out on a great deal.
