The staggering scale of the useless purchases we make has been revealed.
A study of 2,000 people shows the average house contains £1,120.53 worth of items such as sandwich toasters, shoes which only match one outfit and ice cream makers.
Other forgotten purchases include water filters, crockery bought for 'best' and exercise bikes.
Almost half of adults admit their extravagant spending means they often buy things they don't need when shopping, just because the items are close to the till.
In addition to the larger items, three quarters of Brits are frittering cash on purchases they don't need on a daily basis, from takeaway coffees to nail varnishes.
We're also suckers for snacks we don't want but can't resist, special offers on food, and sale items we can't refuse.
Kris Brewster, Head of Products for Skipton Building Society, which commissioned the research, said: "It's surprising to see how much all of these little, everyday expenses can add up to, and how avoidable they can be.
"And if we're honest, those 'one-off' bigger purchases are probably much more regular than we think as we sleepwalk into spending our money.
