Renting a car?
Read the fine print. I saw on tv this morning a guy rented a car from Payless auto rentals in California. It was supposed to have unlimited milege. He did not read the fine print on the contract (which was 3 pages long!) and drove to Las Vegas. Whe he turned the car back in they told him since he drove the car out of state there would be an additional charge of $1 per mile which added $1400 to the $150 rental car. Turns out the car rental co. has GPS systems in all it's cars but that is in fine print too.
