Police were called to Walmart locations in Mansfield, La., and Springhill, La., this past Saturday as shoppers cleaned out store shelves. You see, due to a power outage, max limits on food stamp accounts were lifted. The Supermarket Sweep was triggered when the Electronic Benefits Transfer system went down because a back-up generator failed at 11 a.m. Saturday during a regularly scheduled test. As a result, while the EBT system was down, there was NO LIMIT on the card holders' accounts.

"It was definitely worse than Black Friday. It was worse than anything we had ever seen in this town," Lynd said of Springhill, which is near the border with Arkansas. "There was no food left on any of the shelves, and no meat left. The grocery part of Walmart was totally decimated."

Some customers left with up to 10 baskets full of food. As customers scrambled to get as as much food as they could before the problem was fixed, an announcement was made over the intercom at Walmart that the EBT system was fixed. At that point, people just left... leaving dozens of packed shopping carts in the isles.
