Black Friday is the busiest shopping day of the year where people hit department stores and outlet centers searching for the best deals, often waiting on lines for hours in the cold before the stores even open for sales. The next day is Small Business Saturday, where you could support small businesses by shopping within your own community. While you may not get the best deals you probably won't have to wait on long lines in the cold.
In short: Friday would most likely save you the most money, while Saturday keeps your money local.
