In the downturned economy, parents and schools are spending less on school supplies. A survey from Deloitte found that 64% of consumers said they would spend less on school purchases. Nationwide, parents plan to spend an average of $548 to send their children back to school; and estimates range from a decline of 7.7%, forecast by the National Retail Federation, to as much as 12% in 2009, according to America’s Research Group.
