'I'm a money expert - 10 things you have at home could make you thousands' Marie Kondo told us to get rid of things that don't bring us joy but it seems some of us are struggling to let go.
Now an ITV Tonight programme investigation - Keep, Chuck or Cash in - The Big Clear Out - has identified 10 phones, tablets and computer games that, if sold in working order, could make owners between £2,165 and £2,900.
To contain all those things, people are spending thousands of pounds on storage facilities, garages and even bigger houses to accommodate it.
Many of us who upgrade our phones often hold on to the old ones, relegating them to the back of the shelf or a box somewhere (probably in its original packaging) - but why not cash in on it?.
But you could be sitting on a pot of hundreds or even thousands of pounds - if you would just declutter your home.
