If you have recently agreed to upgrade your membership to Cookidoo® 3.0 you will be charged a prorated fee once you select upgrade. Since you have already paid the original membership fee of $39.00/yr and the upgraded membership is $55.00/yr, you will be charged a prorated amount that will charge the additional fee for the remaining months to access the upgraded features.
The prorated amount per month is the difference between the old membership price and the new membership price divided by the months remaining in your current subscription. The subscription duration will remain unchanged and the next renewal will be charged at $55.00.
