Which supermarket is the cheapest?

With most supermarkets offering discounts and price matches how can we tell which one really is the cheapest? Watch out latest video to find out.

Knowing which supermarket is the cheapest will depend on what you buy – but the various price matches supermarkets promote also make it confusing to know which promise is best.

Today we run through the supermarkets' price offers and see how good they really are.

Tesco has cut the price of 3,000 of its products but an average basket load of shopping has still gone up by £1.34 since it launched its Price Drop back in September 2011.

And it's still more expensive than Asda and even Sainsbury's.

If your shopping bill isn't at least 10% cheaper at Asda than Tescos, Sainsbury's, Waitrose and Morrisons, it promises to refund the difference.

But there are some catches. You'll have to wait until the following day to check your receipt online and you can't claim any savings until the next time you go shopping.

On top of that you must buy at least 8 items and one of these must be an exact match – so for example a bag of young leaf spinach can't be compared with a bag of the same weight of chopped spinach.

Sainsbury's is commonly thought of as more expensive than its main rivals but its brand match against Tesco and Asda products shows it's not always the case.

Your potential savings are calculated on the spot at the till where you'll receive a coupon – although you can't use this until your next shop – which must be within two weeks and on a £20 minimum spend.
Also getting in on the brand matching is pricey supermarket Waitrose with a number of branded items retailing for the same price as Tesco.

If you're fortunate enough to make money from any of these schemes then that's great but be warned that the number of products included within them is only a fraction of the total number of goods the supermarkets sell.

That means the chances of all your shopping items being included in these price promotions is slim.

It seems the best way to cut your grocery bill is still to plan ahead, drop a brand and train yourself off the special offers you don't need.
Incidentally Morrisons is the only main supermarket not to have got involved in the pricing war – but it's the only one to have increased its market share. Proof that straightforward prices are more than enough to keep shoppers happy.
