Spend $50 get $10, $100 get $20, $200 get $50.
Normal exclusions - gift cards, top ups etc (conditions on main page).
One gift card per transaction to a maximum of $50.
Could potentially price match the Noel Leeming $69 portable harddrive and get $10 bonus?
MFCJ5330DW Brother printer currently has a $150 cashback. Warehouse Stationery has it for $249, so after the $50 gift card and the cashback you're only paying $49.
(I checked PriceSpy and there's no lower retail store price to pricematch with.)
