Orbitz offers $30 in Orbucks credit when you add Orbitz Rewards to your Google Wallet account on a mobile device. (Tap "Loyalty programs" inside the Google Wallet app to find the Orbitz Rewards program. New members can register for Orbitz Rewards inside the app while existing Orbitz Rewards members simply have to sign-in.) That's the first such offer we've seen for free Orbucks credit, yielding a $30 savings on an upcoming flight, hotel stay, car rental, or other vacation-related expense. The credit will be added to your Orbits Rewards account within five days, and you'll have 90 days to redeem it. Deal ends December 15 at 2 pm ET.
