If it makes you feel better even I have fallen for things like that once or twice. Once even a guy I knew from a forum owned the traffic service, lots of people posted that it was legit. So I believe it was one of the better ones. However even that one - the traffic was not worth 9.95.
We all learn, usually the hard way, that like Larry said
"if it sounds too good to be true, it probably is."
Be glad your lesson only cost you 9.95 and not 995.00
