"Derby DE blades are quite cheap, and they will last roughly 5 uses each, though that may vary for you. You can buy less than 200, but the only 100 pack on offer cost only a few dollars less than this, so why not.
People tend to advocate blade sample kits, but we are on a budget here, so we are going with the cheapest performer."
