Up to 25% off - some reasonable deals made much better if used with the Spend $75 or more and receive $25 credit deal from Amex. Picked up a big bag of Black Hawk for around $60 (usually around $100 if not on sale).
Online and in store - the homepage says 72 hours so I assume it ends midnight Thursday.
Some fine print:
* Excludes all December catalogue offers and discounts.
* Product/Brand exclusions apply.
* Excludes Prescription Diets and Therapeutic Diets.
Thanks OP the cat dry food is running low so topped up another 15kg for $60!
