RetailMeNot.com one of the  biggest  coupon sites in the United States, today announced it is the first in the deal and discount industry to test a new way to help consumers save money when eating at some of Austin’s top food trucks through March 9-13, 2012, during the SXSW Interactive Festival.

No online code required. No scanning barcodes on a mobile phone. No need for printed coupons. No waiting for your discount.

With this new card-linked coupon technology, consumers can put coupons from over a dozen food trucks in downtown Austin directly on their credit or debit card.

Once a card is registered, consumers can put single-use coupons available at http://rmn.com/foodtrucks on their credit or debit card. As opposed to waiting for their credit or bank statement each month or logging online to see if the discount was applied, the new card-linked coupons identify the discount on the receipt at the point of purchase – another industry first! A simple swipe of the card at participating food trucks enables consumers to experience instant savings viewable on their receipt.

RetailMeNot.com’s “What the Truck?!” promotion enables consumers to save up to 40% automatically when a purchase is made at participating food trucks.

To put offers on your credit or debit card for participating food trucks from March 9-13, log onto http://rmn.com/foodtrucks with a mobile device and follow the easy instructions for linking offers.
