Popped into Bunnings and just happened to hear someone commenting about some cheap USB gear - $3 each. Thought I'd check it out and, sure enough, I found a display with several items ... ALL were $3 each.

I had a look at the plug pack. Solid construction, with USB-A (18W) and USB-C (PD20W) output - the sort of thing I have seen for $20. I asked one of the staff about them and it seems they are a "promotional" item, which, from what I can glean, is like Aldi's "Special Buys". In other words, get them while they're there.
I did grab a couple.

Edit: There was also a car phone holder - also $3.
