Until 8pm tonight, Uber are using their cars to collect donations to go on sale in Save the Children shops.
All the money raised through the sales is going directly to Save the Children, and particularly their Child Refugee Crisis Appeal which supports children who have been caught up in the refugee crisis. The 'giving' service is easy to use, just swipe right from uberX, through EXEC and LUX, to the new giving icon. Then Uber will send a car to you for you to fill with your donations, before taking it on to Save the Children, all for free.
