Apple's (NASDAQ:AAPL) gross profit margins are massive, thanks to the company's incredible brand strength and pricing power. In the retail business, Amazon (NASDAQ:AMZN) is known for its cutthroat low prices. The two businesses' pricing strategies couldn't be any further apart.

A new survey from Consumer Intelligent Research Partners (via Fotune) suggests that the company benefits significantly from increased sales on its website from individuals who buy its Kindles.

In the video below, Fool contributor Daniel Sparks takes a closer look at the difference between Apple's strategy for selling hardware versus Amazon's.
