Re: I can;t for the life of me find where to update my credit card det
When you are in your account there are 5 clickable tabs in a green tab bar the 5th one should say "Billing"
Click on Billing
Then on the far left you will see 3 tabs to select from (Transaction history, Billing settings, & Billing profile)
Click on Billing settings
Within that view you can update your credit card information.
Hope this helps.
