A NATIONAL technical outage halted trading at Woolworths stores, causing chaos for shoppers as their trolleys bank up and some stores closed.
A Woolworths spokeswoman told SBS News the temporary outage hit all its stores.
A Daily Mercury reporter at the scene said services had just been restored and customers were once again flowing through the registers.
Social media posts indicate stores impacted locally include Walkerston and Caneland Central.
"Registers are offline so customers are standing in queues with baskets of food that they can't buy", she said.
There were reports some supermarkets had since come back online.
