I work for Dick's Sporting Goods and due to licensing agreements we only sell home state team merchandise. So in Georgia you will only find UGA, Tech, Falcons gear, etc..... It sucks, i know, and I don't really understand why but you will need to try somewhere else for AU gear.
Check Sports Fan Attic @ Town Center (Kennesa), (678) -354-6845. And there may be a similar type store at Cumberland Mall (I-285 & I-75). I've only seen Auburn Under Armour at Dick's store in Alabama.
