The Challenger Sale was published in Nov. 2011. This video was published before the The Challenger Sale was published. This sales training video addresses how the internet has changed how buyers buy and how sellers need to sell in today's sales environment. Victor uses the buying of a Kindle from Amazon to illustrate his point on selling. Again, this information was developed prior The Challenger Sales model but validates the data found in the book...which is a GREAT book and should be read by all salespeople!
