Because you get additional information.
Kix, if all I am wanting is the app then I go to the website and print it. I can then take it with me to the pistol course so if I have any questions about it, I ask the instructor. Then I can take everything down to my local authority. If I really wanted to be an out-right ass to the local authority, I would take a drive to Middletown and get my finger prints done there (pick up a couple of DPS-46-C's as well). I could then call the local authority to check on the current prices for me to buy my 2nd Amendment right in the People's Republic of Konektikut. Once I know that, I get the money orders, app, & finger print cards together and send the complete package to my local authority via certified mail.
