AUTO RENTAL INSURANCE
Car rental companies often push temporary insurance policies that can cost even more than the vehicle rental itself, so you’ll be paying $30 per day for a service that costs the company $3 to $4. These overpriced collision damage waivers are good for peace of mind, but it’s usually more cost-effective to rely on your own insurance — though in the event of a crash, this will require paying for damages up-front, then recovering funds by filing a claim.
