re: Finally have proof Land O Lakes, Walmart & 2 types of Kroger butter are the same thing.

This is normal for all store brand items. Most of the manufacturing plants can't sell enough product to run their lines all day, so they sell the time to these private label brands. For example, Hunt's tomatoes does a large portion of Walmart/Kroger brand canned tomatoes. They just change the recipe a little bit to save some bucks, but mostly it's almost the same thing.
