Bottom line: TrackItBack is offering 25 miles per dollar spent, which means members can earn 50 miles per dollar spent with this promotion. While obtaining miles by purchasing the lost and found recovery service of TrackItBack is cheaper than buying miles, US Airways frequently sells miles at a 50 percent discount. To purchase 5,000 miles normally costs $137.50 but with the shopping promotion, members can spend $100 with TrackItBack and earn 5,000 miles. If you already have some purchases in mind, double miles sweetens the deal but we don’t recommend making purchases just for the miles with this shopping bonus.
