We recently revealed how a mum from Bristol managed to snag an epic food shop - all for just £1.55.

    Anna Taylor visited her local Sainsbury's where she managed to get a whopping £40 worth of shopping - for under £2 - after purchasing food in the reduced aisle.

    It's a top tip, as most items can be frozen and will not go to waste. However, don't just buy reduced items for the sake of it. Only buy them if you will benefit from their use.

    Anna said: "We used to go in at specific times when we knew there would be reductions, but that was when we were struggling with money."

    MoneySavingExpert Martin Lewis has revealed on his savvy website moneysavingexpert how you can try and bag similar bargains too.

    A top tip was that many staff have the authority to reduce prices at their discretion - particularly goods that are damaged/nearing their sell-by dates.

    If you're friendly, staff are more likely to help than when you're rude.

    Reduction times vary not just by supermarket but by store (and it's particularly dependent on opening times).

    As a rough guide, the first yellow stickers tend to appear mid-morning, and silly-price reductions begin early evening, when stores cut prices by 75% and more, reveals Martin Lewis.

    Here's when MoneySavers revealed to moneysavingexpert website the best times to bag these bargains.

    Final reductions often start around 7pm – and most bargains have been snapped up by 9pm.


    Co-op

    Discounts at Co-op very much varies by store. One former staff member told Martin Lewis items which expire that day tend to have a 50% discount and reductions increase around 5pm, though another MoneySaver said you have to wait until 8pm for 75% discounts.


    M&S Food

    M&S shoppers have revealed how they've seen final reductions at 6.30pm in stores which close at 7pm, and at 8pm in stores closing at 9pm. One person revealed that M&S often marks down items reaching their sell-by date "just after lunch".


    Morrisons

    Shoppers said reductions tend to start late morning or lunchtime. Morrisons told moneysavingexpert there's no set policy though and it's up to individual store managers to decide when and how to reduce items.


    Sainsbury's

    The official line from Sainsbury's is also that the timing of yellow-sticker discounts is "completely store dependent". MoneySavers told moneysavingexpert it's worth starting scanning for yellow stickers around lunchtime .


    Tesco

    Tesco also insists there's no hard and fast rule on discounts, according to Moneysavingexpert. Previous reports from shop-floor staff suggest reductions start as early as 8am and big discounts materialise early evening – but much will depend on individual stores' opening times.
