Arlec Grid Connect Smart Plug in Multi-Function Socket with USB $15 @ Bunnings
Not as cheap as deals non-USB versions (https://www.ozbargain.com.au/node/882445) or the previous Crest Big W deal (https://www.ozbargain.com.au/node/777536) but seems like an OK price for those wanting basic 5V USB ports without needing another socket.
As always with these smart plug deals I suspect YMMV. Just had my Crest w/ USB stop working recently; luckily Big W refunded me without fuss even though it was over 12 months. Try my luck with this one.
Seems to be an almost duplicate of the listing which is at $19.98.
