Has anybody ever used NationwideAdvertising.com ?

I too might be thinking of testing it out, but the one time I tried newspaper advertising (Easy Bank Method), it ailed miserably.

Still never heard of ANYONE doing this successfully....
I didn't experience with the site you mentioned. All websites are look like legitimate .So it is hard to tell whether it is legit or scam. If you are not sure or have any doubts whether the website can be trusted then exit from the site and take your time to investigate further into the website .To check a site is legit or scam you and rating about the site by the Google search. To check the website is secure use the site Webutation.net you will get more information about the website. Get the "whois" information from WhoisXY.com to know the administrative contact, technical contact etc.
