A fake Facebook page pretending to be the supermarket Morrisons has been shared by thousands of Brits on social media.
The convincing page - calling itself "Morrisons UK" - promises people vouchers if they like and share it.
"We're informing every customer that, To celebrate our anniversary, Each person who shares & Comment below will receive FREE £50 Voucher from us," the fake page reads.
It then asks people to validate their entry on a separate website.
At the time of writing, it's had almost 7,000 shares while more than 2,500 people currently like it.
But it's nothing to do with the actual supermarket Morrisons - whose real Facebook page doesn't have "UK" on the end and does have a blue tick to show it's verified.
"This is a scam nothing to do with Morrisons," the supermarket said when asked about the fake page on Twitter .
Some Facebook users have taken matters into their own hands, replying to people who appear to be taken in by the fake page.
Some posted flashing messages reading "Fraud alert" while others have been more blunt - letting people who have shared the message know they're promoting scammers.
In the past, Morrisons has made its position on voucher giveaways very clear.
"We would never ask for your personal details in order to redeem a voucher," it said talking about a past scam.
"If you believe you have been contacted please contact us on 0345 611 6111 or call Action Fraud on 0300 123 2040.
"You can also visit www.actionfraud.police.uk to report fraudulent activity to the authorities."
