Writing killer sales letter is not easy, in fact
it takes knowledge and experience.
Lenny Eng is a great ad copy writer, you should
get his ebook called Confession of a Website Copywriter.
Another well known internet marketing consultant you
should study is Yanik Silver, he's got alot of
research in ad copy writing skills also.
He has a site called instantsalesletter.com
I've read the instantsalesletter ebook and it's
awesome, you should get it.
