Enterprise discounts?

[minnie1928]

A coworker of mine asked me if I knew of a place for Enterprise Rental Car discounts. Being the cheapskate/WDW guru, she knew that I could probably get the information. So now I turn to you guys....I've never rented a car before so this is unchartered territory . How do you get the best deals on rental cars? I'm not sure that she is 100% committed to the Enterprise brand, so I'll take any suggestions!

Thanks so much!!
