Amazon beats competitors using ‘Tesco’ tactics, taking advantage of the final Christmas shopping rush

Amazon only offers the lowest price on its top 20 bestsellers.  On books ranked 21-100 Amazon charges a premium of 14 percent compared to the lowest price alternative.  Amazon earned their low price reputation by playing by a different set of rules than their competitors; other book sellers would benefit from understanding those rules and learning how to apply them to their own pricing.
