Jessicurl Products

Hi all. I usually just buy my products from the local Wal-mart or grocery store, but I was thinking of buying something from the Jessicurl line. I have 3a hair about shoulder length. I'm always looking for ways to enhance my ringlets and increase volume.
Can anyone offer me advice on what Jessicurl product would be a good starting point for me? I was thinking of just buying one thing to start and maybe getting a free sample w/my purchase b/c I saw on the Jessicurl site with any purchase, you can get one free sample!
