I don't know if I'd do raw every other day. It won't be easy on the dogs system. You may end up with some digestive problems.
As far as the prices....I think they are fine. We order from mypetcarnivore who delivers to GR too. But I don't use MPC for more than just tripe and some other organ meat or exotic stuff. The poultry that you have access to, should make up your RMB's(Otto's?) Check out MPC
and compare price. They do charge $10 for delivery but a few of us go in so we split that fee.
