1. Price may be negotiable. You can also call around to multiple car-rental agencies, including lesser-known providers. With the lowest quote in hand, your agency of choice may cut you a deal.
2. Check employer discounts. Your employer may provide you with more than a salary. Ask human resources if your company partners with rental agencies to give you a break on rates. Or ask the agency outright.
3. Inspect your ride. Do the walk-around and check for marred paint, dinged bumpers, fractured windshields and torn seats so you can't avoid paying for what you’ve documented.
4. Get back on time. Your car probably won't turn into a pumpkin, but you're likely to pay for an extra day even if you're five minutes late. Read the fine print and use your cell phone for an accurate time.
