I heard this advertisement on the radio from a marketing company "convert gas to cash" where they send you a registration form and memberships to other discount stores which i never heard of. Soon as i received the discount companies i called and canceled which was a pain in the @$$ and was still charged for some kind of a fee i never heard of.I also sent my registration card for the gas rebates certified mail which was 3months ago and never received!!! they do not have a number you can call.. go figure.
