If you are like me and prefer to own the collector edition’s (CE) physical box, you can get it from Amazon (Diablo III: Collector’s Edition) for about US$100 (S$126) and they do ship directly to Singapore for US$20 (S$25), so total cost including shipping would be US$120 (S$151).
Amazon also sell the Normal Edition for US$60 (S$76) and I am guessing shipping would be about the same US$20 (S$25), so all in all would be US$80 (S$101).
If you are intending to get the normal edition, you are better off getting it locally rather than via Amazon as it cost only S$89. You can preorder at GameScore (email@example.com) or stay tuned to d3.playpark.net for more authorized resellers from AsiaSoft (an official Blizzard games distributor in Southeast Asia).
If you really can’t wait, get the digital version from Battle.net for S$90 as you can start downloading immediately so when the day comes (15th May 2012), the game will be unlocked/decrypted for you to play instantly.
