Savvy supermarket shopper: how inflation hits your weekly shop What this shows is that many everyday items are far more expensive than they were. Far from being a luxury, the white sliced loaf is now 79p at Tesco, up by 7pc on its average price over the past 12 months. The company's standard English unsalted butter (part of the ONS fats and oils category) costs 10pc more than its average price over the past year at £1.49. Six Tesco free-range eggs, which have been an average of £1.50 for the past year, are now 6pc more at £1.59. It's a similar story at Sainsbury's. For those who aren't troubled by the "free range" label, Sainsbury's cheapest Basics eggs (which carry a Freedom Food label) are at their highest price this year - 9pc more than the average 92p at £1 for six. Six pints of semi-skimmed milk are now 6pc more expensive at £1.89. In terms of pennies, none of these increases is massive, but put together they all add up. And experts say that food price inflation is about to get worse. Despite the rise in the price of the Tesco loaf, the real cost of the poor wheat harvest has yet to filter through. For foodies, this week saw another looming pain on the horizon - the poor grape harvest will apparently lead to a 25pc increase in the price of balsamic vinegar. Given that this is one item that really is better aged, perhaps that might be one to add to the shopping list right away. Sainsbury's standard version is already 10pc more expensive than it has been all year - but by next month £3 for 500ml might look like a bargain.
