One of the rites of late summer here in Georgia, where school starts amid the dog days of the season, is back-to-school shopping. Though a boon to retailers, it is a tradition largely dreaded by kids who aren’t eager to surrender their summer fun, and by parents fearing the sticker shock of new clothes that will soon be outgrown and an ever-pricey list of school supplies and high tech gadgetry. In recent years, Georgia parents got a bit of a windfall in late July from the annual tax holiday weekend, allowing them to buy clothes, computers, supplies and various other items without being levied sales taxes.
