I rented 2 cars on Priceline.com to be picked up at Orlando airport. The confirmed Priceline cost was $185.47 (including tax) due on each vehicle at pick-up. At pick-up, we opted for the E-Z toll pass on both vehicles, & told the agent we did Not want the insurance. She said "sign here". She asked if we wanted to add an additional driver, but did not inform that there would be an additional charge, so we said yes. You're in a hurry, you tell the agent what you need and don't need and you're instructed to initial on a small screen. We trusted the agent to carry out our instructions, and didn't read the small print on the tiny screen, grabbed the keys and left. When we received the credit card bill, the charge was $495.99 for EACH car! Calls to customer service with our complaints only yielded a $60 credit! BEWARE!
