Supermarkets add the stickers to products to show they are reduced due to being faulty or close to out-of-date.

And there’s usually a best time of day to head to your nearest supermarket to pick up the best prices.

Tom Church, founder of the latestdeals.co.uk website, has revealed when you should head to your nearest favourite supermarket to pick up bargain buys.

Lidl

Tom said to look out for orange clearance stickers which usually give 30% off in the morning.

He added: “Sometimes there are green ‘waste not!’ stickers labelled at 20p or 70p.”

Tesco

Tom said: “Yellow stickers start in the afternoons, particularly on fresh meat, fish, fruit, veg, and bakery items.”

Waitrose

Tom said the best time to pick up stickered items varies from store-to-store.

He added: “Usually in the afternoon and reductions increase towards closing time.”

Sainsbury’s

Sainsbury’s discounts its products incrementally across the day.

Tom said: “Discounts begin with 25% at 1pm, up to 50% at 5pm and then again by 75% at 8pm.”

Morrisons

Tom said: “The best reductions are in the evening.

“However, you’re better off getting a £3.49 Magic Box from Too Good To Go, which will contain about £10 worth of food.”

Marks & Spencer

Tom said M&S starts stickering up products with yellow tags in the mornings.

“As M&S has a higher price point, net savings can be bigger than other supermarkets,” he added.

Co-Op

Tom said: “Yellow stickers are found throughout the day and it varies by store. Final reductions are 75% off.”

Iceland

Tom said yellow-sticker discounts vary across Iceland stores.

He added: “On fresh foods yellow stickers can be found from the mornings.”

Aldi

Tom said: “Clearance stickers are red and applied in the morning from 8am with 50% off. “This may increase to 75% as food approaches its use-by date.”

Asda

Tom said: “Reductions start in the mornings but there may be second rounds of discounts from 7pm.”
