Morrisons has upset customers by increasing the price of their carrier bags to 30p - the third price hike of the year so far.
The price hike is being piloted by the firm at some of its stores, with a view to introducing the new price tag at all of its stores throughout the country if successful, writes MirrorOnline .
It would represent the third price hike for plastic carrier bags at Morrisons this year.
They increased in price from 10p to 15p in January, and rose again to 20p only in April, according to the Sun .
Many customers are pretty unhappy about the change and have taken to Twitter to let it be known.
"I’ve just spent 30p on a carrier bag in Morrisons and I am shocked and upset," Abbie Colclough tweeted.
Kristian Hicks felt the same, tweeting: "30p for a carrier bag Morrisons really??? What’s next, a rental charge for the shopping trolley?"
Another customer felt the charge was forcing people into using paper bags.
"30p for a carrier bag? You having a laugh? But hold on I can have a paper one for 25p??" he tweeted.
"Seriously, at least Dick Turpin had the decency to wear a mask."
The paper bags are made in Wales using sustainably managed forests and are strong enough to carry up to 16kg of shopping.
The move comes as the supermarket looks to make a permanent switch to paper bags in an attempt to cut down on single-use plastic.
Morrisons chief executive David Potts said: "Our customers tell us that plastic reduction is their most important environmental concern.
"So in a company-wide effort for the last 18 months we've been working aisle by aisle to take out unnecessary plastic wherever possible."
Morrisons has been voted the most environmentally responsible company in the UK at the Responsible Business Awards for its work on plastics reduction.
