Rentalcars.com appears to offer an attractive deal, including insurance but when you actually go to pick up the car, the car provider they have assigned does not deliver the car demanding you purchase insurance directly from them. Effectively this amounts to forced purchase of insurance twice over and if you don't do it they don't give the car. So when you walk away from the deal rental cars.com system does not let you cancel and then you can't get your money back. This is tantamount to outright theft just that there is no recourse except credit card company that I am now struggling to reach to disallow the charge.
