Britons spend around £43 a month on pointless items.
According to a new poll by OnePoll.com, they found almost a quarter of British people struggle to put money aside for a rainy day and on average squander more than £31,000 during their lifetime.
Half of those polled choose convenience over cost - including buying a sandwich rather than making one themselves.
Another 53 per cent admit to spending money on unnecessary things despite knowing they can't afford it, while less than half the nation set a budget.
Louise Harper-King, from OnePoll, told the Metro newspaper: ''We've all had those months - where payday seems to crawl into sight and when it eventually comes around, our well-earned pounds are frittered away on bills and debt.''
