The discount chain, which started life in Liverpool, is among Britain's fastest-expanding retailers. ‌On its website, it states: "As a company, we have decided to only sell reusable carrier bags at 20p (40p in Northern Ireland), as we believe that this is the cheapest and most cost-effective reusable carrier bag on the high street. According to GOV.UK: "Retailers of any size (large, medium, small, micro and airport retailers) must charge a minimum of 10 pence for single-use carrier bags in England. ‌"Only large retailers are required to record and report the number of single-use carrier bags they sell in England.
