Dollar General is a beast. They've grown same-store sales for 31 years in a row, straight through recessions, pandemics, wars, and bubbles. I'm not aware of any retailer that can match its record. Not even Walmart can match that record. Dollar General's growth isn't just steady. It's counter-cyclical too. It grows fastest when the economy suffers most, so it's no surprise then that 2020 was a banner year. Same-store sales grew 16.3%, the most in thirty years.
