Sarah Shaoul, who owns Black Wagon, a children's clothing and toy store, has tried to warn other businesses on North Mississippi Avenue against the daily deals companies. "They hit up all these small businesses, and all these owners are wearing tons of hats, and they don't have the resources to really vet the offer," Shaoul says. "All they know is, they see their neighbors jump off the cliff like lemmings, and they're doing it in droves, because Groupon says this is the best marketing thing you can do."
