Hey, thanks! A Good Portfolio has multiple plans, with payment that can be made through Paypal.
The Pro links will take you to Paypal, where you can put in your login information, it'll ask for a confirmation, and then take you right back here.
If you don't yet have a Paypal account, there's an option once you're there to set one up. It's super easy, and free.
Or, of course, you're welcome play with a free account.
