Been in the market for a dual desk mount and just noticed these two deals via Mwave. Quick google search puts the regular price in the $150-160$/$140-$150 range if you account for shipping costs.
They're the same price during the sale but the heavy duty version supports up to 10kg/30" per arm vs. 8kg/27" for the regular version.

Hard to find actual customer reviews, but this video (regular version) as well as the comments sealed the deal for me.
$24 shipping to Brisbane is a bit tough to swallow - this maybe a good one for Sydneysiders.
