Can you still buy Ipod Nano's from Aldi rouse hill?

As of my last update, the iPod Nano has been discontinued by Apple since 2017, so it's unlikely you'll find new units at any retailers, including Aldi Rouse Hill. You might find some used or refurbished models through online marketplaces or second-hand stores, but availability can vary. It's always a good idea to check directly with the store for their current inventory.
