Despite ingredient change, still great food @ great price

Another reviewer chastised Loblaws for a slight change in the main ingredients claiming that the food now lacks protein. They moved potato up one spot in the ingredients list, however the first two ingredients are still Salmon.
The PC Salmon and Potato dog food still has as much or more protein than most of it's competitors, and it is less than half the price.
It's nutritional analysis is as good or better than foods similar to and including Blue Buffalo and Performatrin Ultra. It has high protein, high fiber,and low fat.
