The Plugin Site

Hello,
I'm hoping that you can assist me on plugins. I'm working on a digital tag & the tutorial I'm working from request to use Penta Jeans, Lokas 3D shadow. Would happen to know where I can get these plugins.
When I searched for Penta Jeans, it direct me to your page. I have already downloaded 2 of your programs, but Penta Jeans wasn't in the 2 programs.
I would greatly appreciate your assistance.
Thank you.
Fran
