Outdoor World, Inc. is a retailer of sporting goods, equipment, and accessories for use in outdoor sports and camping. This week, the manager of Outdoor World places an advertisement in the newspaper "Coleman Tents- 50% off-This Week Only! William, in the market for a tent, saw the advertisement and went to Outdoor World the first day the ad ran in the AJC. When William arrived at the store, the manager explained to William that the Coleman Tent was temporarily out of stock, and instead tried to sell him the Tectonic Tent, which is much more expensive. Does the manager's conduct constitute a deceptive trade practice? What law governs unfair trade practices?
