Amazon has this SanDisk Ultra II 480GB for US$135.99 + shipping (US$5.53 to WA) for another 5 hours (until 3pm WST).
From Original SanDisk sale post
Shame about the Aussie dollar, but works out to around $190 delivered, so still a bit to be saved there.
Just take note, it's shipping time is listed as "Usually ships within 2 to 4 weeks."
SSD prices seem to be crashing. wonder if its a marketing thing, or a scale thing now that adoption is becoming much more universal.
i look forward to the day when they are at or near parity with mechanical drives.
