Just bought this, and this was the best deal I could find. It's discounted from $47.70 to $44.75 at the store, and one gets the coupon above for signing up to the newsletter. Best on eBay I could find was $2.92/kg delivered (for 25kg), and Aldi's is $3.33/kg (for 3kg). Don't look at chemist and Colesworths prices (unless for a laugh!).
