It's been found that Brits hoard an amazing £81.6 billion of unwanted items.
The study, commissioned by online lender MYJAR, revealed the average Brit will have unwanted goods worth £1,600 lying around their home. With three in 10 labelling themselves a 'hoarder', it's also not surprising that the loft or garage will normally only get cleaned once a year.
Even more surprising were the one in 10 who said they had never given their old possessions a proper purge.
A spokesman for MYJAR commented: "We believe this research highlights a problem with overspending."
"People feel the pressure to buy things they don’t really need. There’s a general lack of financial education too, so a lot of money is spent unnecessarily."
"On average, people have unused goods at home that they could sell on, but of course the best way to keep your finances in check is not to spend unnecessarily in the first place."
The study also found that one in five do not sell pre-loved possessions as they're not aware of how much they're worth, while over one in 10 have binned something, only to find out it was worth much more than expected (this was an average of £484).
It also emerged that two fifths have old mobile phones stashed away, while over a quarter have held on to their gaming systems and just under half have held onto old books for a period before selling them.
Other popular options included vinyl records and vintage clothing, while just over one in 10 have old VHS tapes. Nearly half of those polled via OnePoll said they ended up regretting their impulse purchases, while six in 10 say they end up never using what they've bought.
Over 50 per cent said they regretted impulse buys, as they feel haunted by mistakes - in fact six in 10 said they will never what they've bought.
More than half said they ended up wishing they hadn't bought something as it was an impulse buy, with over a fifth saying they regretted their choice - simply as it costs too much.
The items Brits are splashing out on include signed books and pictures, beds, a model railway, drum kit and a Dr Who Tardis - some of the more unusual things the nation have made a pretty penny from selling.
