Retailers in the UK may be enjoying one of the brightest sales periods of the year due to the spread of the foot and mouth disease. With the countryside virtually out of bounds many people are packing up for the weekend and heading into the city's shopping centres. Over the Easter weekend, Manchester's Trafford Centre saw extra shoppers boosting trade in many of the shops, some with as much as a 20 to 30 per cent increase in turnover compared to the same time last year.
