Last year supermarket Morrisons announced it had teamed up with the Too Good To Go app.
The initiative allows the retailer to sell boxes of unsold for food for less, meaning customers can save money and reduce waste at the same time.
And it appears many thrifty shoppers are utilising the offer and sharing their food boxes to encourage others to do the same.
Amy Barnett, 26, from Chesterfield, is just one of these customers, and has told how she managed to get a "magic box" from Morrisons using the Too Good To Go app.
Explaining the process, Amy told money-saving community LatestDeals.co.uk : "The boxes are just £3.09 per box - it’s the equivalent of a children’s lucky bag but with food! They’re fun and they’re saving food going to waste.
"I decided to buy the box to save wasted food, to share with others and to spread the word, and because I like the unknown!"
She added: "The box had a variety of cakes, a celebration cake, lots of different fruits and vegetables, including some I hadn't tried before, so it was nice to try something new.
"There was so much fruit in it, which my little girl loves, too, and it was all fresh.
"My little girl and I host coffee mornings at our house each month for charity and we have one this weekend so the cakes in this particular box have a good enough date for the coffee morning."
Amy believes the boxes could have been worth up to £20.
She explained: "I felt really good not just because of the money-saving but because I’d tried new foods and stopped food going to waste.
"It's really difficult to get the boxes, you have to be on the app at the right time - they sell out in seconds - so you need to be on at 6.10pm, refreshing like mad."
The co-founder of LatestDeals.co.uk , Tom Church, said: "Too Good To Go is taking over the world! This app not only fights the battle against wasting perfectly good food, but also lets money-savers get their hands on huge boxes of food for a fraction of their usual price.
"If you don’t get a Morrisons box the first time round, don’t be disappointed: keep refreshing your app every day around 6pm and you’ll eventually get lucky.
"Another similar money saving-trick is to look for the Too Good to Waste fruit and veg boxes in Lidl. These are £1.50 and have five kilograms of wonky fruit and veg. Perfectly healthy and good to eat."
