Charities are set to benefit from a new scheme that will see surplus food stock which has been sent to a leading UK supermarket donated to vulnerable people.
Asda said its new partnership with food redistribution charity FareShare is the first of its kind and will mean an extra 3.6 million meals will go to those in need every year.
When surplus stock that is not needed is received by supermarkets, it is usually returned to the manufacturer and often goes to waste, according to an Asda spokesman. The new scheme will see it sent to Fareshare instead where it would then go to local charities.
FareShare chief executive Lindsay Boswell said: "This partnership involves the redistribution of surplus food at unprecedented levels never before undertaken by a retailer on this scale in the UK.
"We also know that there are more people turning to charities for food than at any other time in FareShare's history. This initiative will mean we can provide more food to more charities and will enable us to feed even more people at a time of real need.
"Not only will this programme have immense environmental impact by diverting food away from the waste stream, it will also save hundreds of charities millions of pounds a year.
"They will be able to reinvest these savings into providing additional support services for their beneficiaries."
Barry Williams, chief merchandising officer for food at Asda, said: "It's hard to believe that in this day in age, nearly four million adults and children in the UK go to bed hungry each year.
"Food poverty is a very real problem and it's getting worse, not better. Through our new supply chain model and work with FareShare, I'm proud that we're able to help feed millions of vulnerable people around the UK who would otherwise go hungry."
He said he hoped other supermarkets would follow suit.
Seven of the craziest supermarket glitches
Surplus food to help vulnerable
One of the most popular glitches, was a wine deal at Tesco back in November 2012, where a series of offers clashed, leaving a bottle of £9.99 wine selling for £1.50.
The 'three wines for £10' deal apparently clashed with a '25% off when you buy six or more bottles' deal. The 25% was accidentally taken off the original price rather than the reduced one, leaving the wine at rock bottom prices. Deal-hunters cleared the shelves around the country.
Perhaps the most popular glitch from Tesco came in June 2011, when instead of taking £4 off the cost of a £20 case of beer, the supermarket accidentally started selling the cases for £4. The ensuring rush was nicknamed the 'beer stampede'.
Sadly not every supermarket pricing glitch comes with such a happy ending for consumers. In March last year the bargain-hunters thought their luck was in, when Tesco accidentally priced the new iPad at just £44.99 instead of around £650. Sadly it spotted the mistake before shipping the goods. The small print on its website meant it could refuse to sell at this price, and refund their customers instead.
In September 2012, Asda was responsible for one of the most expensive glitches. The Asda Price Guarantee offered vouchers to customers who could have got their shopping cheaper elsewhere.
However, when certain trigger products were in the basket, the supermarket massively under-priced the shopping at other supermarkets, and offered huge vouchers to shoppers. In many instances the vouchers came to roughly the same as the cost of the shopping.
In April, a mistake on their website resulted in Tesco selling 8 packs of Bulmers cider 568ml bottles for £5 - rather than a six pack for £8.
Deal-hunters snapped up the deal online, and had varying degrees of success. Some had their order delivered in full, others had six delivered for £5 - and were able to negotiate their way to another two, while others were offered six for £5 or their money back.
October last year saw one of the most famous glitches, when Tesco Terry's Chocolate Oranges were subject to two deals at the same time, and the price dropped from £2.75 to 29p. There were plenty of people getting chocolate oranges last Christmas.
A buy-one-get-one-free deal went awry at Tesco in March. People putting four tubs of I can't Believe It's Not Butter or Oykos yogurt packs into the trolley were only being charged for one.
Soon the online deal-hunting community was in action, with one person bagging 50 tubs of butter and 22 pots of yogurt for £8.79 - a saving of £133.89.
