Budget Pet Products have their Advantix 9 packs at the price of 6 packs! Delivery was free to Sydney.
I.e. Advantix blue (25+ kg) 9 packs is $74.43. The cheapest 6 pack I've seen from other retailers at the moment is around $70 after delivery. So this is really good price outside of manufacturer's promotions such as buy 6 packs get 3 free.
Our vet recommended Advocate. Is Advantix any better?
