Very loyal customer

Summing it up, Amazon's competitive advantage lies within the customer-centrism, the personalized services and the ability to react to changes quickly, in fact to initiate these changes by being innovative on its own. A good example for this is the "e-nightmare before Christmas": in high peak seasons, there were often delays in deliveries as the distributors dealing on behalf of Amazon were backlogged with orders. Hence, Amazon build up over 4 million square feet of warehouse space in the US to have its own distribution centers and by 1999, 99 % of the holiday orders on Amazon.

com arrived on time (Gillespie, 2005).This example clearly shows Amazon's strong ambition to satisfy the customers which is quite successful as now they have a very loyal customer base which is continuously cultivated by lowering prices, giving special offers and adding new features to the Amazon.com website (Gillespie, 2005). Amazon is a brand name everyone knows, a site that is easy to navigate and the company has build up a reputation for reliability (Gillespie, 2005).However, Amazon still has to face competition.

One of their most important competitors is most certainly Ebay Inc., although it is not an online retailer but an online bazaar. Basically, Amazon.com, Inc. and Ebay Inc.

are using the same data warehousing technologies. However, Ebay Inc.'s business model differs from Amazon's as it mainly concentrates on auctions (Datamonitor, 2008). Ebay Inc. has been holding a monopolistic position on the online marketplace via auctions for years, but in comparison to Amazon.

com, the company did not come up with any innovations recently (The Economist, 2008). Ebay Inc.'s profit margins are shrinking whilst Amazons' are steadily increasing, even if they are still smaller than Ebay Inc.s' (The Economist, 2008).In 2007, Amazon recorded an increase in revenue of 38.

5 % and Ebay Inc. stated an increase in revenue of 28.5 %. Ebay Inc.

's customer base is shrinking whilst Amazon's is increasing due to its strong brand name and the named customer-centrism, which also exists on Ebay Inc., but there to a far smaller extent. Amazon used the last decade to build up trust that orders will be delivered on time and cheap enough to keep customers coming back while on Ebay Inc. it is still sometimes the case that customers can not be sure what they will get (Gillespie, 2005).

 Apart from the competition with Ebay Inc., Amazon also has to face rivalry with a bookstore that is not completely virtual: Barnes ; Noble is a well-known publisher and book retailer operating mainly in the US.The company entered the online book market later than Amazon, namely in 1997 (Data Monitor). Through the physical stores it still maintains, Barnes ; Noble have higher overheads and their online offer is about ten times smaller than Amazon's (data monitor).

Amazon can offer a much larger selection of for example book titles as it does not have to stock all the goods but relies on distributors instead (Laudon and Laudon, 2006). The figures make it clear: Barnes & Noble announced an increase in revenue of 2.7 % in 2007 against the named 38.5 % of Amazon.All in all, it can be said that Amazon's competitive advantage is rooted in its flexibility and the relentless focus on the customer. Amazon constantly aims to increase customer satisfaction and convenience and invests the money it saves into new technologies and into keeping up with the times.

Amazon always tries to be one step ahead of its competitors, something that for example Ebay Inc. missed for a long time. The constant data analysis combined with a flexible management allows well-based decisions and one can say that Amazon has optimized its performance by relying on a data warehouse and new information technologies rather than on physical warehouses and stores or on its monopolistic position.ReferencesBacheldor, B.
