Common questions

How is weekly billing converted?

Weekly cost is multiplied by 52 for an annual estimate, then divided by 12. A weekly cost of 12,000 KRW equals 52,000 KRW per month on this basis.

Is this the exact amount charged this month?

No. These are comparison equivalents. Billing dates, calendar payment counts, discounts and payment fees can change actual charges.
