Check off-brand companies

They include Ace Rent a Car, Pay Less, and Midway, which you can find at www.carrentalexpress.com or www.carrentals.com. Also consider shopping at www.hotwire.com, a discount-travel site that offers deals without revealing the name of the rental agency until booking is completed.

Ask for discounts

They're generally available to members of AAA, AARP, Costco, Sam's Club, labor unions, professional associations, and other groups.
