Satechi USB-C Multimeter retails for US$29.99 (S$40) on their own website. However, it only retails for US$22.95 (S$31) on Amazon.
Both sites shipped directly to Singapore. Satechi will ship to Singapore via USPS Commercial ePacket for US$12 (S$16) while Amazon will ship via Aramex for US$4.55 (S$6).
Bought the Anker Micro USB to USB C Adapter from Amazon for US$6.99 (S$10). It comes in a pack of two, so that makes it US$3 (S$5) each, excluding shipping.
It does ship directly to Singapore for US$4.49 (S$6).
