I can’t purchase any package with Offset! It doesn’t let me continue when I select the ‘Custom Payment’ option!

Ans: Please click on the ‘Maximum Payable’ column, then input the amount you wish to use from your Offset account.

Alternatively, please make sure that you have sufficient balance in both the Offset and Deposit account, as the balance may erroneously round up sometimes (for example, 499.8 HU showing as 500 HU on the purchase page).
