The Google USB Type-C to USB Standard-A Plug Cable has been out of stock for quite some time. I managed to buy it when it just got back in stock on 9th November 2015. Because it doesn’t ship to Singapore directly, I have to ship it through a freight forwarder like HopShopGo.
The retail price is US$12.99 (S$19) excluding shipping fees from HopShopGo and comes in only one length which is 1m. It is a USB 2.0 cable and hence the data transfer speed will be capped at 480Mb/s.
