I've been tracking the price on this motherboard for the past 2 months. This is the lowest it has been since the COIVD shortages and the cheapest Mini-ITX of any B450/B550 boards right now. Added bonus of a rear USB C port makes it a pretty good deal in my eyes.

Buyer beware: stocks in mid August so you might not receive it till early September.
ASRock B550M-ITX/AC is also available for $211.20 +Delivery from Newegg AU, if you're specifically looking for a B550m ITX board, though I'm put off by some of the reviews.
