If we had to use just one word to describe the climate surrounding this year's back to school shopping season, we would use the word restraint. This is not to say that all of the air is out of the balloon, but it wouldn't hurt if it was propped up a bit. It's restraint, mainly in the form of moderation that's the big story for back to school this year. This year, students and their parents plan to spend an average of $608 on back to school-related purchases, representative of a 10% decrease compared to last year.
