German discount supermarkets Aldi and Lidl have entered a price war regarding their ‘Back to School’ uniform ranges. Lidl began by offering a package containing two polo shirts, a sweatshirt or jumper and trousers or pleated skirt which would be sold for £3.75. In response, Aldi then cut its own package down to £3.75 ahead of the impending summer holidays, which are set to begin in the next two weeks.
