I am using an ONS voucher to purchase the ONS/ONCC Chemotherapy Immunotherapy Certificate Course, but it says I owe $20. Why do I owe more money?

The all new ONS/ONCC Chemotherapy Immunotherapy Certificate Course and the Fundamentals of Chemotherapy Immunotherapy Administration Course increased in cost by $20. ONS vouchers that were purchased after November 5, 2018 are not course specific, meaning they were purchased for a specific amount as opposed to a specific course. ONS vouchers can only be redeemed for the amount of the voucher is worth. 

Additional vouchers can be purchased to cover the difference in cost or payment can be made by credit card.
