it is through http://www.guntrust.com/, you get a code. it is $79 if you want to amend it and add more people later, I had a couple more questions to ask them.
guess it is just a form. they are asking $199 on their page, and with FL carry you get both the form and a membership for $100.
here is the process and their disclaimer
