Ground sirloin and ground round are the same thing. They just package it with a different label. I see a lot of meat departments claim that they have the best meat. Everyone uses the same meat. Well I hope that that was an eye opener for you.
Fresh seafood is a contradiction in terms.
Then the fish are brought to a fish market. Then the fish are sold to a local delivery route. Then the local delivery route person has to deliver it. The freshest seafood is the fish that you buy frozen. On the ships that are out to sea for weeks at a time they fillet them and flash freeze them right on the boat.
