By far, the best way to generate stock bills for the late game is by mass-producing Buck Capsule A. This product benefits from the multiplication of buckflower powder and sandleaf powder. It sells significantly more than the Buck Capsule B and is not all too difficult to go from producing Buck Capsule B to A.
