50 percent off standard rates at EnterpriseWhat's the deal? Some car-rental offers are so good right now that renting might be worth considering even if you have your own vehicle. Perhaps you own a gas guzzler and would rather drive something that gets better mileage - or you simply want to save some wear and tear on your car. For example, customer favorite Enterprise is offering a "weekend special" that amounts to 50 percent off standard weekday rates. The offer is valid through May 21.

What's the savings? Depends on which type of car your rent. The discount is valid for cars, economy through full size, rented Fridays to Mondays.

What's the catch? The offer is available only at certain locations in North America, but airports are not among them.
