Phrases That Sell: The Ultimate Phrase Finder to Help You Promote Your Products, Services, and Ideas

I bought this book because we are revamping our website and I thought it could be useful to make our content more compelling but I was really disappointed. The book offers a list of supposedly "ultimate" phrases to promote products and services but in anyone with half a head on their shoulders could come up with the same or even much much better ones and I didn't find one phrase in the book which I thought was original and worth buying it for.

"Gems" include "proven effective", "a touch of class", "enroll now"!!??

It may be useful for marketing students or anyone who has never had a job but frankly I wouldn't waste your money.
