We do pretty good in tough times, but we do very well in good times as well. Reporter: Family dollar has been doing well for more than a half century. Levine's father opened the first store in charlotte, north carolina, in 1959. In the beginning, family dollar sold only things that cost a buck. But they abandoned that years ago. Today, roughly 90% of their products are less than $10. About a third of everything they sell is not made in america. What do you say about that, that all of this stuff comes from china?

We needed to get what she needs it. She's out buying what she needs. Reporter: You keep saying she. Who is she? 87% of our customers are women. We think about her all the time. Customer, customer, customer. Reporter: She is the noun in just about all of your sentences. To me it's dna. You're getting four times as much for 50 cents less.

Good to see you. Reporter: Howard levine is already a millionaire many times over, but 50 years after he walked these aisles with his dad, he says he still shops here. This is what I bought.
