A savvy shopper says she couldn't believe her eyes after compiling a list of Asda items to see how much they'd been hit by inflation.
Julie McHamish put together a spreadsheet documenting how much her shopping list cost from the supermarket this week compared with this time last year, and was left speechless.
Some store cupboard staples have nearly doubled in price in just 12 months, Julie has revealed, while almost every item on her shopping list bar two things had gone up in price.
The price tag on olive oil has soared by 70%, closely followed by pitted black olives which were up by two thirds (67%) of the original cost.
Recent heatwaves in Spain, which produces roughly half of the world's olive oil, has hit crops hard, driving up prices of the essential ingredient.
Cucumber prices were also up by 67%, Julie found, while other items also seeing big hikes in cost over the past year included cheese (60%), houmous (55%) and semi-skimmed milk (43%).
Bread and potatoes were also up by 40% and 36% respectively.
Sharing her shock on Twitter, Julie wrote: "Because I am nerdy, I looked back at my online shopping order [at] ASDA a year ago to compare to today's prices. WOW!"
She added: "Almost all items are over 10% more expensive than last year! Kellogg's Cornflakes are just[!] 5% higher & Maryland Cookies are the same price!"
Alcohol-free Guinness and Maryland cookies were the only two items on Julie's list which were the same price as the year before, although she added the cookies were "probably more than likely overpriced to begin with".
She added: "Surprised that nearly everything was above 10% though!"
Julie's findings, which were examined 12 months apart between March 24 last year and March 23 this year, come as recent Office of National Statistics data revealed inflation rose by 10.1% in the year leading up to January 2023.
The Ukraine war, surging global energy costs and Brexit have all been attributed as reasons for soaring costs in the UK.
Olive oil, skimmed milk and sugar are among the items ONS highlighted as having risen the most.
An ASDA spokesman said: "All supermarkets have been impacted by global inflationary pressures which has increased the price of key ingredients.
"We’re working hard to keep prices in check for customers and we remain the lowest-priced major supermarket - a position recognised by Which? in their regular monthly basket comparison, naming Asda as the cheapest supermarket for a big shop every month for the last three years.
"We recently announced we would be freezing the prices of over 500 popular branded and own label products, more than half of which are fresh meat, dairy, fruit and vegetable products until the end of May."
