Extra 5% off their EOFY Stocktake Sale in-store or online. The only exclusions shown on their site are gift cards and pre-orders.
0.95% surcharge on card & PayPal payments.
Stack with the current factory cashbacks from Canon, Sony, Fujifilm etc make some sweet bargains.
E.g. Canon R8 $1787 after $150 cash back, R6 II $2826 after $200 cash back, Sony A7 III $1593 after $400 cash back!
Hardcore OB'ers can price match Sony but there is a chance you might miss the cut-off date for their cash back (02/07) if store ships late because their invoice date is their shipping date (happened to me once).
Edit: Looks like DD introduced a Payment Handling fee around 1% when I tested check out unless I use Latitude or Zip.
