Retailers such as OfficeMax and Staples are offering penny promotions for back-to-school shoppers. The retailers hope that customers will come in for the 1-cent deals on back-to-school items and pick up some other items, too. "This is the only time of year we do a penny," a Staples executive said. "Unfortunately, there are a lot of other people out there fighting for back-to-school business. Drugstores. Discount stores. We needed a way to get the word out and break through the clutter. It doesn't matter what the item is. One penny is a great deal."
