A third of young people are considering quitting their jobs to sell goods on smartphone apps, research has revealed. A survey of 2,000 18 to 24-year-olds found clothes (49 per cent) were the most popular item to sell via their mobile, followed by footwear (24 per cent) and video games and consoles (24 per cent). And there has also been a significant proportion of young people tapping into trends such as retro cards or fitness equipment, advice or classes to make a few quid. Overall, 67 per cent of young people have sold at least one item on a smartphone app since March 2020. Almost a third (31 per cent) of respondents have sold 10 or more items, according to the research by O2 Business, which offers small and medium-sized business (SMB) customers tailored flexible packages specifically designed to help businesses as they evolve.
