Food shops are always a huge weekly expense for families, but one mum managed to bag a bargain with a special way of shopping.

Amy Barnett, 26, from Chesterfield, took home a 'magic box' from Morrisons filled with £20-worth of food for a fraction of the price.

She used the app Too Good To Go, which aims to cut down food waste by connecting shoppers with the chance to 'rescue' food that otherwise would be thrown away.

Support worker 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!"

Amy added that the box gave her an opportunity to try new foods that she might not have usually bought on a trip to the supermarket.

"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," she added.

"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.

"Some things needed using ASAP so be prepared to make a quick soup or something like that. Other items I gifted as I didn’t want to throw them away, as that defeats the object of what the boxes are for.

"I am also going to look into gifting some items to a food bank or homeless shelter but I need to check their policies on some foods being over their best before date.

"I feel the boxes were worth at least £10 and to be honest at full price probably £20 but obviously they had a short life on them.

"I felt really good not just because of the money-saving but because I’d tried new foods and stopped food going to waste."

However, Amy said the boxes sell out immediately so you have to act fast.

She continued: "They are really difficult to get the boxes, you have to be on the app at the right time - they sell out in seconds! They sell out in a minute so you need to be on at 6.10pm refreshing like mad."

Alongside supermarket boxes, the app works with restaurants in Manchester city centre to offer left-over food that again would otherwise go to waste.

Prices range from a few pounds and have set collection times.

Food waste has a harmful effect on the environment and is responsible for 8 per cent of global greenhouse gas emissions.

Too Good To Go say there's food lost or wasted along the chain from farm to table; including all the resources that went into making it.
