Been cheaper in past, but seems to be a good price for now.
~$26.35AUD per TB.
"but what about warranty". good question fellow ozbargainer. YMMV, but when I ordered some ultrastar drives a few years ago I messaged Amazon US specifically about warranty and they gave me their guarantee that they would honour the warranty period. this was despite the actual storefront seller of the product saying they wouldn't (they went on to say Amazon shouldn't be selling their products to people overseas hah), and the WD website not coming back with anything in their warranty checker (presumably because it's not a consumer drive).
My NAS is pretty much full so I need to start swapping for higher capacities so this is tempting, but personally I will probably wait for Black Friday sales and see if this gets any better.
Edit: thanks for the edit, had my currency in AUD and Amazon adds some "exchange rate guarantee", so didn't notice the cheaper pure USD price.
@phoenx not sure if you know but the GB currently being organized for higher capacity drives here
