The fine print tells you that they will charge your credit card monthly when you sign up to look up a vin number for your car. I signed up and noticed four months later that I had been charged $15 x 4 = $60! Unless you are a dealership or used car dealer, etc and need this service all the time, I would avoid signing up. Otherwise you need to somehow remind yourself to call up and cancel your "subscription." Also, they will not refund your mistake of not reading the fine print, even though you never used their service again and they continued to charge you.
