Customers with Electronic Benefits Transfer cards cleared shelves at Walmart stores in two Louisiana cities on Saturday night, when the cards were not showing limits, KSLA News 12 in Shreveport, La., reported.

The influx of shoppers in Springhill and Mansfield led to empty shelves in the stores. The glitch-inspired shopping spree ended after a few hours—the EBT cards started showing the limits again around 9 p.m. and customers left their carts mounted with food before the check out, according to the report.

EBT cards deliver government benefits electronically with a set spending limit.
