Will Dollar Stores Rule the Retail World?

Last Monday, Dollar General, the nation's largest dollar store chain, posted a better-than-expected profit, helping boost the company's stock, which is up 15 percent year to date. And earlier this year, the discount retailer announced plans to open its 11,000th store by the end of the 2013, an impressive figure for a discount retailer. The only other companies to boast store counts that high are fast-food chains like McDonald's and Subway. And Dollar General isn't the only dollar chain to have had success in recent years.
