I swear it was every 3-4 months we'd get a 5% off discount code and it would stack on the buy 2 get 1 free + 20% off sales and make for an actually alright price on media.. what's happened to them? Tempted to unsubscribe from the 5 JB HIFI emails I get each week because most of them are "ZERMAHGERD HERE'S AN EXCLUSIVE DISCOUNT VOUCHER" on something nobody would ever pay full price for like a $1200 scooter.

The last 5% off was last month 9th of October, although you didn't need the email as the code was generic this time. It stacked with some other deals, eg P30 Pro & Galaxy S10.
Yesterday's code deal - Google Chromecast (3rd Gen) $44.25, Google Nest Hub Max $261.75 was also a popular one (generic code again).
