I have been eying on the Griffin PowerDock 5 since it was announced back in January 2013. But unfortunately it wasn’t released till last month (July 2013).
The Griffin PowerDock 5 is retailing for US$99 (S$126) directly from Griffin’s website. I doubt it will come to Singapore anytime soon. Griffin offers free shipping within the US and they do ship to Singapore directly and for the PowerDock 5, the cheapest shipping is about US$12 (S$15.30) without tracking. But I did not choose that option, instead I shipped it to HopShopGo, which is a freight forwarder and paid US$20.08 (S$25.50) for DHL Express shipping to Singapore.
