Shoppers say costs are actually rising(Image: MArtin Keene - PA Wire)

Shoppers are not benefiting the highly-publicised supermarket 'price war', with many customers claiming they are actually paying more.

Tesco, Asda and Sainsbury's have all announced major price cuts in their stores in the last month, and we wanted to find out what impact this was having on shoppers' bills.

We polled around 1,500 MSN Money users to gauge their opinions and, remarkably, almost seven in 10 (69%) said they were now paying more than before. Just one in 20 (5%) said they were enjoying lower bills, while roughly a quarter (26%) said they had noticed no difference in terms of overall costs.

What the supermarkets are claiming
Let's take a quick look at what deals the supermarkets have announced. First up, Tesco pledged £500 million for its Big Price Drop, which it said would see costs of 3,000 products slashed, including essentials like milk and bread.

Sainsbury's followed suit by announcing its Brand Match campaign, in which it promises to refund the difference in vouchers if a shopper is able to buy branded (ie, non-Sainsbury's) goods cheaper at Asda or Tesco.

Asda then waded in with a £5 voucher for anyone shopping at the store, as well as a wide range of price cuts.

It all sounded like great news for hard-pressed shoppers, but it remains unclear how much they are benefiting - if at all.

Tesco already embarrassed
While most MSN users feel like they're losing out at the till, our findings also seem to be backed up by research from the Grocer magazine.

The publication carried out a mystery shop on a basket of 33 staples at Tesco and found that the bill was actually £1.34 more expensive than it had been before its Big Price Drop.

It was embarrassing for the supermarket and disappointing for customers in equal measure.

If you don't feel you can rely on your supermarket to cut costs in these difficult times, you should take matters into your own hands. Read our guide to cutting the cost of your supermarket shop.
