Department store, John Lewis, is reporting an increase in sales with figures up by around 6.1 per cent on last year. But the store, whose slogan is "Never Knowingly Undersold", says it could still do better and it is investing time and energy in improving its performance in the run-up to Christmas. Top seller is hard furnishings, which includes beds, computers, televisions and white goods, which were up by around 7.4 per cent, followed by fashion at around 5.2 per cent. A spokesman said: "We are working hard and getting ready for the pre-Christmas rush. There are a lot of things to take into account, including price deflation. "There are retailers doing better than us and there are those who are doing worse. We are doing OK, but we would like to do better." The John Lewis Partnership currently operates 25 department stores in and near major towns and cities across the UK from Aberdeen to Southampton and from Bristol to Norwich.
