You don't get any discount in this case though. You're still paying $2-3/lb for bruised apples that are like you said literally waste at that point and $2-5/lb for chicken that if you picked out yourself would be of higher quality.
Even if they did give you a price break for lower quality food. They'd still do things like give you a pineapple that will never ripen before it rots like we received last week.
