Popeyes brought back it’s Chicken sandwich on Sunday more than two months after it first sold out. The sandwich originally launched in August and quickly became a big hit for the fast food chain, selling out in two weeks during a Twitter feud with Chick-Fil-a. The sandwich was so popular that it’s sale was still 17% higher than average two weeks after it sold out. It apparently took Popeyes so long, because they had to lock down suppliers for the brioche bun and small chicken breast, The Wall Street Journal reported earlier. Popeyes` decision to bring it back on Sunday appeared to be a marketing stunt designed to reignite the feud with Chick-Fil-A after Chick-Fil-A tweeted out something for national sandwich day, which happened to be on a Sunday, the one day a week that Chick-Fil-A is closed.
