J Sainsbury has reported a small rise in H1 profits, helped by its store refurbishment program. Like-for-like sales are up 6% in Sainsbury's UK stores, its third consecutive period of strong growth. Although it's worth noting the figures are compared to a very poor H1 2000, the retailer seems to be turning its fortunes around. Plans to make better use of information mined from its loyalty card scheme in setting stock levels should help this process.
