A new supermarket has become third cheapest behind Lidl and Aldi for the first time in our comparison of basic groceries.
We've been tracking prices of the same eight essentials at the six main supermarkets for almost a year now.
For much of that time Sainsbury's has been among the most expensive, alongside Morrisons.

In fact when we first started monitoring prices last March, Sainsbury's held the unfortunate title for around two months.
But it's had quite a turnaround over recent months - so much so that it is now third cheapest in our ranking behind Lidl and Aldi.
This week's bill comes to £11.67 for the shopping basket, which includes a two-pint bottle of milk, a loaf of bread, a pack of mince, a pack of chicken, tea bags, coffee, beans and butter.
Last week Tesco was in third position, just a penny cheaper than Sainsbury's, but has this week increased the price of its two chicken breasts from £2.50 to £2.55, bringing its overall bill to £11.71.
Morrisons has also increased the price of meat, putting its 500g pack of mince up from £1.89 to £1.99, making it £11.77.
The only other increase is a 1p rise on the Just Essentials beans at Asda, which, with a bill of £11.84, is spending the fourth week at the bottom of our chart.
Sainsbury's has been getting quite some attention of late and last week we reported how shoppers said they were switching to the retailer because of its Aldi Price Match scheme and its quality of food.
Our own big shop there proved why it's become so appealing to shoppers looking for both budget prices and big brands in the one place.
Sainsbury's CEO Simon Roberts has already shared his vision for it to become 'as cheap as Aldi' and says it is seeing 'more customers coming back to us from the discounters'. But that's a claim which Aldi refutes, saying industry data suggests the opposite.
At the moment Sainsbury's is still 31p more expensive than Aldi in our comparison, with its bill at £11.36. Lidl maintains its cheapest position for the fourth week running, with its shop totalling £11.23.
