I missed out on the 30% off code but found this one from an expired deal that is still working.
Stackable with 5% for auto-delivery and extra 10% for first auto-delivery for a total of about 35% off.
Said to be applicable to only 1 item, but you can order 2 or more of the same item and get discount for all of them.
Would be great if I lived over east! Would be $35 for a 4kg bag of cat food. Sadly, the delivery costs kill it for me.
