Customers in Sainsburys had a super discounted shop after a voucher glitch meant they get could get all their shopping for free.
The Sainsbury’s app offered the coupon on Monday, meaning shoppers rushed to purchase discounted food.
But a glitch meant customers could scan the voucher multiple times at self checkouts until the total cost owed reached £0.
Some shoppers piled trollies high with luxury goods, with footage showing one man stockpiling basics such as toilet paper.
Footage from a store in Gants Hill, east London shows an argument breaking out between two shoppers and staff who denied their use of the voucher.
They repeatedly scanned the voucher, causing the total amount owed to drop every time.
Despite staff arguing the code has been cancelled, the customer insists: ‘It’s allowed, Sainsbury’s is allowing coupons.
‘Take it off the system. If it’s not allowed, why is it still on the system? It’s allowed, it’s a coupon.’
‘I am using a coupon. Disconnect it from the system and I won’t use the coupon. The system allows me to use it so I’m using it. If it’s a frauded coupon, how is it on the Sainsbury’s app?’
In the White Rose Shopping Centre in Leeds, another clip shows a long line of trolleys piled high with groceries.
A woman can be heard saying: ‘This is ridiculous, look at this. This is why it stopped. Look at this, they don’t buy so much in real life.’
The filmer moved down the line as the more trolleys piled with goods come into view.
It is not clear whether these were seized before or after the glitch.
The footage was captioned: ‘A glitched Sainsbury’s coupon was released on the app yesterday where it allowed customers to get all their items for free.
‘Those who found it before Sainsbury’s did made sure to take the p***.’
A spokesperson for Sainsbury’s said: ‘We have seen an increase in fraudulent coupons in our stores and we have processes in place to detect and block them.
‘We also have in-store detectives monitoring for fraudulent attempts and we are working closely with the police on this issue. We continue to accept genuine coupons and vouchers.’
