As part of its annual One Two Free promotion, National Car Rental is launching its new “One Two Free” Twitter sweepstakes, offering Emerald Club members more chances to earn points toward a free rental day.

Through Nov. 14, qualified U.S. participants can enter the Twitter sweepstakes by tweeting how they would use a free rental day and using the hashtag #OTFsweepstakes. Five winners will be randomly selected to receive 600 promotional points — equivalent to one free rental day through One Two Free.

For example, a customer can tweet, “I would use my free third rental day to visit the coast! #beachday #OTFsweepstakes.” Participants can post their tweets Wednesday Nov. 1 through Tuesday Nov. 14, 2017, with the hashtag for a chance to win.

The One Two Free promotion awards registered Emerald Club members one free rental day for every two qualifying rentals. Each free day covers the base rental rate (time and mileage) only, according to the company.

To provide more opportunities to earn free days, this year’s promotion offers additional points to members who complete any five bonus opportunities through One Two Free, as well as to members who complete their third qualifying rental during the promotion. One Two Free will run through February 28, 2018, and the redemption period will end on June 15, 2018.

As a bonus opportunity during the sweepstakes, National is also giving registered Emerald Club Members the chance to earn an extra 100 bonus points by clicking the Surprise Bonus Opportunity within their One Two Free dashboard.
