How can I skip the payment upon registration of the user to the blog?

I created a Free Levels on the Levels Option of the Pro Sites.
My problem before the user can use or enable the site/blog they created they need first to go to check-out page.
This is Free Level so I don't need them to do the check-out for the payment.
I also didn't use the Pay To Blog module.
Can you please help me and direct me to the right path.
