>> A behind the scenes war for your wallet, I'm Reuters' Jeffrey Dastin. Behind every single price you see when shopping online is in fact an algorithm. Retail has changed dramatically in the past decade. It's not the same experience where you go to a store, you see a price, and if you go back to the store later in the same day, the same price will be there.
