I have no experience in writing sales letters, so I read several articles about them and read some that supposedly convert well and tried to use some similar language, ideas and design elements.
The site is Towering Tips, and the book is "Towering Tips," a guide to increase tips for waiters, bartenders, etc.
I'm open to all criticism and any ideas to improve. I haven't sold anything, but I know the sample size is extremely small (a couple hundred visitors via AdWords).
Thank you in advance!
