It is never 100%, things age out companies change up to avoid the savings, and so on. It does work though and I have save well over $1,000. It is worth the free install for sure.

I have had this for years and as far as I can tell it has never ever actually saved a dime. Claims to find a discount but never ever actually applies one.

I cannot get past "Let's get Started". Won't allow me to put UK down (just USA and Canada) and won't accept my postcode. Useless. Am uninstalling.

It does not automatically run.

Best credit card I've ever had.
