// Which? found Asda had the lowest average prices for branded groceries
// Waitrose and Ocado were the most expensive
Shoppers could be paying four times more for the same branded grocery products depending on where and when they shop, according to an investigation.
Which? found Asda had the lowest average prices for branded groceries while Waitrose and Ocado were the most expensive, in a survey of 493 items at six major supermarkets last year.
Shoppers could pay almost four times more for Lavazza Qualita Rossa Ground Coffee (250g) at Ocado on different days, with the price ranging from £1.30 on 63 days to £5 on 130 days – a 284 per cent difference.

- Extra costs when buying from EU retailers should be clearer, says Which?
- Aldi named the UK’s top in-store grocer
Ocado said the price fluctuation was an error that had been corrected.
Muller Light Greek Luscious Lemon yogurts fluctuated substantially in price at Sainsbury’s between £1 and £2.75 – a 175 per cent difference – at roughly three-week intervals.
The same product was also available for £1 or less in at least one of the major supermarkets for about 85 per cent of the year, Which? found.
Other price variations included Carte D’Or Vanilla Ice Cream and Loyd Grossman Tomato and Basil Sauce at Asda, of 133 per cent and 125 per cent respectively.
Jordans Country Crisp Four Nut Cereal at Tesco cost £1.35 on some days and £3 on others, a variation of 122 per cent.
The investigation also analysed pricing across 19 product categories, finding the cost of branded cakes and biscuits fluctuated by 48 per cent on average.
A 10-pack of Cadbury Chocolate Mini Rolls at Asda had the biggest price difference, ranging between £1.20 at its cheapest but more than doubling to £2.60 on certain days.
Juices and smoothies varied in price by 41 per cent on average, followed by cooking sauces (38 per cent), crisps (36 per cent) and cereal (35 per cent).
Across all the 19 categories, Asda had the lowest average prices for branded groceries, making it the best option for shoppers who prefer branded items but do not want to pay over the odds.
Waitrose was the most expensive supermarket for branded items in eight categories including energy drinks, ice cream and tea, and Ocado for seven categories including juice drinks, coffee and cheddar.
Almost all the products in the investigation varied in price and could be found discounted at one or more supermarkets at any time. However, a Which? survey found one in five shoppers are confused by grocery promotions and the majority (73 per cent) would prefer consistently low prices.
Aldi and Lidl were not featured in the investigation as they stock fewer branded goods.
“Our research reveals just how wildly food and drink prices can fluctuate from day to day, meaning people are at risk of massively overpaying for branded groceries depending on when and where they shop,” Which? retail editor Ele Clark said.
“We would recommend keeping an eye on the prices of your favourite products and stocking up when they’re discounted to avoid paying over the odds.”
An Ocado spokeswoman said: “Ocado is committed to offering customers the best range, service and value in the market.
“As part of this commitment, we are proud to offer over 49,000 products – more than any other supermarket.
“The fluctuation in price for the Lavazza product was due to a technical error and has since been resolved.
“The regular price is now back in place and is in line with most other major grocery retailers.”
Waitrose said: “We constantly review prices to ensure that we offer the highest quality products at fair prices, combined with fantastic customer service.”
