BUY2HILLS
20% off purchase of 2 or more Hills Science Diet Products @ Budget Pet Products.
E.g. 2x Hills Science Diet Oral Care Chicken Rice And Barley Recipe Adult Dry Dog Food 12kg (1139HG) ($100.82 @ auto-delivery price) comes to $161.32 or $80.66 per 12kg bag.
This appears to apply across product lines. I.e. discount still seems to apply on cart with 1x Hills Science cat food + 1x Hills Science dog food.
Cashback may apply (despite coupon code not appearing on Shopback, my sale tracked).
The kicker for those who haven't used auto-delivery before, is that it appears to stack with their current 20% off first Hills Science auto-delivery. The above example with first auto-delivery seems to come to $121, or $60.50 per bag.
