WATCH: 🇬🇧Britons are stocking up, with bottled water and hand sanitiser high on their shopping lists. A video circulating online appears to show shoppers rushing and arguing over bottled water at Costco. The government’s “Be Ready” campaign urged households to keep 3 days of food and water at home in case severe weather or cyberattacks disrupt essential services. In the 10 days following its launch, sales rose compared with a year earlier: Hand sanitiser - up 83% Bottled water - up 67% Tinned and jarred food - up 37% Retail researchers say the broader trend reflects GRADUAL stocking up, rather than 'PANIC BUYING'. MORE shoppers are adding essentials to their weekly shop. However, NOT everyone can afford to prepare. A government survey found 29% of UK residents cannot afford to keep a few days of food at home.
