JB's 20% off banner
20% Off Board Games
JB Hifi have 20% off all Board games (Most/All? cards games as well). Some pretty good deal to be had as their starting prices are pretty decent (usually not RRP) already. If you have a perks voucher you can get some of the cheaper games for really cheap.
Edit: Just to add, as magpiejay has said some of JB's prices aren't great so if you're aren't an avid board gamer and are unsure of the pricing for the games, best to check the price at BoardGameOracle. They have detailed price history, a little like the camels for Amazon.
Sadly JB-Hi-Fi aren't great for board games, unless you want 200 licensed versions of bloody Monopoly you'll never actually play. (Who is still buying Monopoly?)
That said, they do have a handful of worthy games. They aren't usually competitively priced, so be sure to check the price of the title you are after against the prices at other retailers at: https://www.boardgameoracle.com/en-AU
