I accidentally joined in an online community of Aussie shoppers and found this very interesting conversation among its members. Please have a look at the captured screen below with a strong attention on the statement red-circled by me with a star on it 😀
I think this is a good experience for you guys, especially amateur shoppers like me, when visiting all electronic stores, including big ones such as Harvey Normans, Radio Rental, Dick Smith or JBHifi.
Enjoy your shopping time 😉
