According to the Wall Street Journal, discount/single-price point stores like Family Dollar Stores Inc. (NYSE: FDO), Dollar Tree Stores Inc. (NASDAQ: DLTR), and the soon to be KKR owned Dollar General Corp. (NYSE: DG) are growing in popularity [subscription required] with consumers, reporting solid same-store sales growth and expanding sales of food products. According to Family Dollar CEO Howard Levine, "The low-income customer is always stressed and always strained. When things like a minimum-wage increase happen, that's a great benefit to them. When gas prices come down, that's a great benefit to them, and conversely when they go the other way, that has a negative impact."

Because of sky-high real estate prices in my area, we have no dollar stores. There used to be one in a local mall but it got replaced by a jeweler. I'm not kidding. However, anytime I'm traveling, I go to a dollar store, not because I'm "always stressed and always strained," but because it's fun. I was recently driving with my brother and we passed a Family Dollar and I practically ordered him to turn the car around. He reluctantly agreed with only this protest: "You are such a loser."
