Wendy's has launched a new promotion offering free French fries every Friday for the rest of the year. The deal, which starts today (April 19th), will allow customers to enjoy any size of fries free of charge with any purchase, with no minimum price required to use the deal. The promotion is good for in-store or mobile orders, but has to be activated through the Wendy’s app and loaded onto a payment card prior to purchase. Including today, there are 37 Fridays left in the year for fans of Wendy’s fries to take advantage of the deal.
