There is a well known trader who goes shopping with his familiy and whenever he sees a new shop / retail chain etc. doing well he will invest in that. Same thing he does in reverse - when a chain is well regarded and the shops are empty he will short it. For years I have shopped with Amazon. Trading books are not that cheap and I have bought (at a guess) 75+ books from them in the last few years alone. Because I live not in the US I thought "Great, they now have digital books and I do not have to wait a week or two for it to arrive". Somewhere between my machine (stock standard XP Professional installation) , Acrobat reader's "Digital Activation" and Amazon the digital book got stuck and was not downloaded onto my machine. Yet Amazon states that " their records show that it is succesfully downloaded" 1) You cannot return a digital book (yet you may pay the same rpice for it as the physical book) 2) You cannot contact Amazon directly, except through a myriad of vague and useless help forms 3) Even when offering to pay for the shipping costs and ordering the same book they will not do this 4) Digital shipping - you wait 36 hours before getting an answer to a complaint, negating the whole fast delivery scene In short: I am out of pocket and Amazon does not want to know (Very good business concept. Yeah..... NOT! ) Lesson learned: Never order anything that gets delivered "electronically" across the web when you can take physical delivery of it. Warning to long term traders: See the first paragraph, make your own conclusions.
