Discount and Economy operate in many cities and you have to be very careful, very cheap online rates but bait and switch on fees. Generally a very hard sell on insurance. At one office in FLL they wanted me to take insurance at $35/day because I did not carry proof of insurance from my car, I walked out.

I carry a Chase Sapphire card and had 1 windshield crack issue and it was very easily handled. The bill was just $35 CDN, but I wanted the experience in dealing with CC insurance and mine was as good as advertised.
