How can I update my credit card numbers or expiration date?

Here's how to change the credit card details for future Base Camp Trading charges, whether it's just updating the expiration date or providing a completely different number or new card. 

Use the instructions at the following link to reach the Manage Billing screen, and then select the individual ongoing charge you want to update.  An example of the recurring Platinum Membership is shown below.  Locate the credit card currently on file for this recurring charge at the left of the screen, under Payment Method, as identified by the card type and its last few digits. Click on the pencil icon that's just to the right of the card details, and you can modify the credit card details.  Once the new card details are saved, close the billing dialogs.
