Black Friday occurs on the day after Thanksgiving each year. On this day, retailers offer huge sales in order to get customers to their stores throughout the Christmas season. The name was once used to describe the heavy pedestrian traffic that occurred the day after Thanksgiving, but later, it became known as the day that retailers were "in the black." This is an accounting term which means turning profits. The opposite is to be "in the red" which means having a loss.

Though Black Friday is still weeks away, many retailers have begun Pre-Black Friday sales. Walmart has initiated a "secret Saturday" sale which offers about twenty items at extra low prices.
