For what it is worth (and in this case quite a bit) I had a look at one our library books "How Linux Works" and thought that I would need to buy it and use for reference. John Mc said buying from O'Reilly's, members get a 20% discount. I checked Dymocks Auckand and they could get me one for $94.95 and would take 6-8 weeks to arrive from the US. So I ordered it from O'Reilly's website for $US30.36 (including discount) The only shipping option was DHL (courier) and it was not until I had given my credit card details and the invoice was created that I could see the shipping charge. $US31.60. Then I checked on Amazon (never a good move to check other prices after the tranaction has taken place). Below are the comparisons. Dymocks Auck $NZ94.95 + postage to me O'Reilly's $US30.36 book $US31.60 shipping (Supposedly 2 days but it hasn't arrived after 4 days) $NZ83.00 total Amazon $US25.05 Book $US11.98 Shipping (1-2 vweeks) $NZ37.03 Total
