I found this short video.  It is very helpful in learning what the 4Ps are and how they are the gears that drive success in business.

WATCH IT!

Product, Place, Price, & Promotion are the 4Ps.  

Offer Products customers value

Configure Price including all $ transactions

Include a wide range in Promotions

Place = proper distribution

I agree, that marketing to so many, is just the promotion aspect of the 4Ps.  I can see now that marketing encompasses all of theses elements.  Each part equally important in building sales.
