Are there any discounts offered on the required fee?
Yes there is a discount given if 3 or more institutions pay together (and in a single bank transfer). For example, if 4 institutions pay together, then the total amount to pay would be $4000 USD instead of $6000 USD.
In addition, if an institution pays for 2 consecutive years (the current year and the following year) then the total amount would be 2000 USD instead of 3000 USD.
