Generally, if you use an auto ship option to maximize the initial price then Pet Direct is often one of the cheaper places to get pet food. Can cancel this later on if you don't want the products shipped every x number of weeks.
For example, the popular Addiction Mega 20kg bag is $142.49 (auto ship) so $131.49 with this voucher.
Free shipping with $79 purchase.
