Undertaking weekly or monthly grocery shopping will be a regular occurrence for millions of families. However, covering the cost when someone reaches the checkout is perhaps the most important aspect of all.
In this sense, the British who use cash to make their payment should note an essential update.
The change to keep in mind relates to the validity of £20 and £50 notes, and ignoring it could mean someone’s transaction is rejected altogether.
From September, £20 and £50 paper notes will no longer be considered legal tender.
In recent months and years they have been replaced by polymer alternatives – a type of plastic – in a new design.

Paper notes can be deposited in UK bank accounts and some post offices can still accept them.
All notes withdrawn will continue to be exchanged by the Bank of England.
Chief cashier at the central bank, Sarah John, said: “We want to remind the public that they only have six months left to spend or deposit their £20 and £50 paper notes.
“Over the past few years, we have changed our banknotes from paper to polymer because these models are harder to counterfeit, as well as being more durable.
“Many of these paper notes have been returned to us and replaced with the £20 polymer featuring artist JMW Turner, and the £50 polymer featuring scientist Alan Turing.
“However, if members of the public still have any of these paper tickets in their possession, they should deposit or spend them while they can.”
The move to polymer banknotes was undertaken for a number of reasons.
The first is that banknotes are resistant to dirt and moisture, and thus stay in better condition for longer.
The new banknotes also have more detailed security features, making it more difficult to counterfeit them.
Finally, polymer banknotes also have tactile features, allowing blind and visually impaired people to use them.
