Is there a monthly usage limit or expiration requirement for bulk-purchased selections?

There is no monthly spending limit.

The conditions for expiration for bulk purchases are as follows.

• If you started using the plan before December 2022
  
  • This applies to plans such as 60 Selection, 120 Selection, 360 Selection, and 600 Selection.
  • When the contract period expires, the subscription will expire regardless of whether you continue to use the plan. Therefore, it cannot be carried over to the next contract period.
• If you start using the service after January 2023
  
  • 100 selections and 1000 selections bulk purchases are eligible.
  • If the contract is to be continued after the contract period ends, the remaining amount can be used as is. However, if the contract is terminated without continuing the contract, the selections will expire even if there are remaining selections.
