Walmart Is Selling One Of Patti LaBelle's Sweet Potato Pies Every Second, Thanks To A Viral Video

Sales of Patti LaBelle's sweet potato pie have surged at Walmart locations across the country, ever since one YouTuber posted a "review" of the pie last week that turned into a moving rendition of the iconic American singer's "Isn't It a Shame."

The video, which has since been viewed more than 1.5 million times, prompted LaBelle fans and sweet potato pie devotees alike to flock to Walmart for a taste. The pies, which were "not selling" before the video, went on to sell roughly one pie per second for at least 72 hours, Walmart spokesperson  John Forrest Ales confirmed to Yahoo Food.

Since then, Walmart has been hard at work trying to replenish the stock at locations where LaBelle's pie has sold out. If that's true of a Walmart near you, "We're really sorry about that," Ales wants you to know. "We're looking at where stores are out and how we can quickly move pies to that area."
