When we analysed supermarket prices in December to find out which supermarket was cheapest for a basket of goods, we found that Asda was significantly cheaper than any of the other supermarkets.
Every month, we analyse prices to discover which supermarket is cheapest. For December, we found that Asda charged £161.16 for 84 items – this was £8.04 less than the next cheapest supermarket.
Tesco has changed its price comparison scheme and now deducts money at the till or as you pay the bill online, so should charge the same as Asda for our basket. However, you need to buy at least ten items to qualify for the scheme.
The most expensive this month was Waitrose, which charged £25.62 more than Asda.
You might be surprised by the order of the other supermarkets – you can see how they line up by going to supermarket prices compared.
The supermarkets in 2016
The rise and rise of the discount supermarkets looks set to continue in 2016, with Aldi revealing plans to open 80 new branches this year – taking it to a total of 700.
While this is still a long way behind Tesco’s 3,500 stores, supermarket shoppers are continuing to embrace Aldi and Lidl’s budget approach. The discounters have grabbed market share from the big four supermarkets (Asda, Morrisons, Sainsbury’s and Tesco).
However, what do Aldi’s customers think about it? We ask 10,000 people each year how they rate their supermarket for everything, from value for money to the trolleys. Find out how Aldi scored in our Aldi review, where you can also find out about Aldi Best Buys.
Supermarket price comparison schemes
If you want to save money on your weekly shop, it’s not just as simple as who’s cheapest – as many supermarkets have price comparison schemes. This means that if some or all of your shopping would have been cheaper elsewhere, you may be offered a voucher, points or money-off for the difference.
This is how the different schemes stack up:
- Asda checks against Tesco, Sainsbury’s, Waitrose or Morrisons. It will give you a voucher for the difference if it isn’t 10% cheaper
- Ocado price matches against Tesco and will give you a voucher for the difference
- Sainsbury’s has a price match for branded items only and compares against Asda
- Tesco checks branded prices only against Asda, Sainsbury’s and Morrisons. It deducts any discount automatically at the till
- Waitrose price matches Tesco on branded items and these are the prices it sells for.
To calculate the average price of our basket, we used data from the independent shopping website Mysupermarket. We include discounts, but not multibuys.
