Which supermarket is cheapest? Tesco, Aldi and Lidl compared

Analysis by Which? found Aldi offered the lowest prices in March for a basket of 95 everyday grocery items, reinforcing its position as the go-to retailer for budget-conscious households.

The data shows Aldi customers paid significantly less compared to rivals, with stark differences across the board:

• £26.75 cheaper than Tesco (even with Clubcard discounts)
• £28.47 less than Sainsbury’s (including Nectar prices)
• £29.70 cheaper than Morrisons
• £64.38 less than Waitrose

Even compared to Ocado, shoppers could save nearly £50 on a single shop.

Over a year, that could add up to more than £2,500 in savings for regular customers.

This comes as major retailers including Aldi, Lidl, Morrisons, Asda and Co-op are slashing prices across everything from vegetables to full roast dinners, with some items dropping as low as 4p.

This could be one of the cheapest Easter shopping periods in years – with meals from £1.25 per person and toys at half price.

But most deals are short-term, meaning shoppers may need to act quickly before stock disappears.

The biggest headline-grabbing deals are on traditional Easter veg.

Aldi shoppers can get potatoes, carrots, onions, swede and parsnips for just 8p and 4p each, bringing the cost of a full veg shop to under 50p. Products include British white potatoes (8p, 2kg), British carrots (4p, 1kg), XL garlic (8p, each), brown onions (8p, 1kg), British swede (4p, each) and British parsnips (4p, 500g).

Morrisons has carrots, parsnips and swede at just 4p, with savings of up to 96%.

These offers are only running for a limited period in the run-up to Easter, meaning availability could be tight as demand surges.
