But it seems many of us ladies are losing far more than we realise – about £470 a year to be exact.
A study by Barclaycard's deals site bespokeoffers.co.uk has revealed that Brits are wasting a whopping £23billion every year.
And you probably won't be surprised to hear that women admitted to being the biggest culprits, with a third of us failing to return unwanted clothes.
Unused gym membership is another example of how we squander our hard-earned pennies, costing almost five million people an average of £787 every year.
Meanwhile takeaways are making a dent in our purses to the tune of £324 a year.
The report by Beat My Price – a new service from Barclaycard that offers shoppers unique online discounts – showed that we are too busy to seek out better deals.
Sarah Willingham, Consumer Champion, explains: "Being financially savvy really doesn't need o be time consuming. It's amazing how the small things can soon add up."
But now there is no excuse to be so careless with our cash. Ronnie Denholm, managing director of bespokeoffers.co.uk, says: "We know exactly how hard it can be to keep track of everyday expenses. Our online shopping tool takes the hassle out of bargain hunting and busy Brits could say up to 15 per cent on every purchase."
