Shoppers are going hog wild for Piggly Wiggly's retro pig merchandise

Merchandise from a regional grocery store chain with locations across the Midwest and South has become a hot commodity.

Nicola Miller, of Suffolk, England, will detour as much as 50 miles to visit a Piggly Wiggly when she's in America, hoping to add another T-shirt featuring the iconic, cheerful Mr. Pig to her collection, Food & Drink reported.

Miller first encountered the mascot in the 1978 film "Close Encounters of the Third Kind," which features the retro pig face in the film's final scene.
