That twenty markup is fare; but for those in need of the extra kit, only. But for those that do not need it is a lot. Even more, those not needing it are the largest part of the potential demand. Think twice if adding the international set may be in the best interest of those making the bulk of orders for the set. Previous group buys proved demand for international tend to be extremely low, even for those sets that sold hundreds. I wonder if ANSI users may want to pay extra for something they will never use. Even worst, with special color kits like this that do not match any OG sets.
