UK Consumers Shopping on Mobiles Phones Set to Top £19 Billion by 2021

British consumers are set to spend £19.3 billion (US$30 billion) using their mobile phones and tablets within the next ten years, compared with £1.3 billion spent today, according to new research by Barclays Corporate. The convenience of amending shopping lists, making payments and arranging delivery times via mobile means food and groceries remain the most popular 'on the go' mobile purchase, ringing up sales of nearly £300 million for supermarkets and grocery stores this year. By 2021 this figure is expected to top £5 billion.
