Getting a free Uber ride isn't usually easy. Unless you get a referral from a friend, you typically have to get that gratis trip outside of the app. You'll have a much easier time after today, though -- Uber is launching a promotion with Capital One that makes every 10th ride free (up to $15, that is) if you pay with a Quicksilver or QuicksilverOne card. The offer only lasts until March 2017, and you'll have until April 30th, 2017 to use your free travel, but it could save you quite a bit of cash if you regularly hail Uber cars to get around town. Let's just hope that these kinds of promos spread to other partners and become more of a mainstay.
