http://www.smartbizsavings.com/. It is a great way to save on rental cars, motels, and many other items. With their discount I got my room at the Red Roof Inn South for $39.99 a night from Tuesday Aug.31 - Monday Sept.6. Without the discount it is $49.99 a night; that's $60.00 saved for my 6 night stay.
