The recession has sent a new type of customer to Wal-Mart and now the retailer is doing everything possible to keep them shopping there.
   It's the customer making a higher income. Wal-Mart is redesigning hundreds of stores to give them cleaner, wider aisles, fresh color schemes and better lighting. It's also beginning to carry more brand names and it's improving its electronics department.
   In this tough economy, Wal-Mart says it's seeing more customers who are financially better off but looking for bargains. Those shoppers spend, on average, 40 percent more than traditional lower income shoppers and the company wants to keep those high-end customers coming back.
