National Car Rental sent out teaser emails earlier today to get Emerald Club members to preregister for One Two Free promotion that will return in the fall 2015.
The promotion is a free one day rental code for every two rentals that you make during the offer period (still unclear) in the United States.
There is not yet public link to sign up for this offer.
The offer dates were in:
2012 – August 20 (2012) – January 31 (2013)
2013 – September 9 (2013) – January 31 (2014)
2014 – August 20 (2014) – January 31 (2015)
This is the best car rental promo out there that seems to be returning again this year. If the previous three earning dates are any indication, the promo will begin in the second half of August and end in January 2016.
