With the Photography package, you get the very latest versions of Photoshop and Lightroom for $9.99/mo (one year contract).
Thanks for the clarification of price. It is not clear to me on the Creative Cloud/ Lightroom /Photoshop download page if it is possible to ADD Lightroom to an existing Photoshop contract. Are you able to help with this question?
If you're paying $9.99 per month, you must have the photography package. Open up your creative cloud application and you should be able to install Lightroom from the Apps tab.
