I'm pleased to announce that as of now we are accepting direct credit card payments for paid upgrades. In the past, all payments have gone through Paypal. To purchase an upgrade via credit card:

Click the "Upgrades" tab in your admin panel
Select the upgrade you want and click "buy"
Click the "Purchase via credit card" option
You will be directed to our secure credit card processing page to enter your information

As always if you have any questions or problems please let us know by posting in the support forum.

Enjoy
