Aldi has launched an online calculator at www.saveamillionwithaldi.co.uk, to show shoppers how much they can save by shopping for clothes at the grocer's stores.
Aldi said that a woman of 35 living in London could make a lifetime saving of £1,101.76, if she switched to buying her summer clothes with the supermarket.
Aldi UK MD Paul Foley said: "Our number one priority is simply the quality and price of the items in the customer's trolley. We can pass on excellent savings to our customers by cutting out all the unnecessary extras that the big four [supermarkets] hide on the grocery bill. We have steadily seen savvy shoppers coming through our doors and during the current economic climate, we are becoming an even more obvious choice."
