Hertz created a new social media campaign "Share it Up" to encourage customers to share the company’s promotions on their social media accounts. With each click of the “Share It Up!” button on Hertz’s Facebook page, users will unlock discounts that they can use on rentals.

Each promotional coupon increases in value the more it is shared within social networks — rewarding Facebook fans, Twitter followers and email subscribers. All fans who share the coupon will able to take advantage of its savings.

The campaign began on April 11 and ends April 30 and can be accessed on Hertz’s Facebook page. The promotional coupons are good on car rentals until July 16.
