We charge a 200 yen application fee  regardless of the number of packages being consolidated.
Independent of this, we charge 300 yen for consolidation of the first two packages and an extra 300 yen for every package after that.

Example: When consolidating three packages
200 yen (application fee) + 300 yen (second package) + 300 yen (third package) = 800 yen (total consolidation fee)
