PriceGrabber®, a part of Experian, just released additional results of its Back-to-School Shopping Forecast survey, revealing that 48 percent of shoppers plan to spend $250 or more on back-to-school purchases, and 25 percent will spend $500 or more. This is a modest decrease from back-to-school budgets in 2010, when 56 percent of consumers indicated that they would spend $250 or more and 31 percent planned to spend $500 or more. Conducted between May 12 and 19, 2011, the survey includes responses from 2,612 U.S. online consumers.
