Remember when Coca Cola came out with New Coke. Looks like Kraft has just done the same with the great mayonnaise that many of us have used for our entire life.
It appears they changed out the lables a while back. I remember thinking it was odd that they went from a really decent looking label to a cheap, generic looking label they are using today. When the labels switched I though the mayo did too but it had not ( at least not yet ).
It seems to be that they got folks used to a new label and then started phasing it in to stores thinking we might not notice. Well I got my first jar of it the other day and noticed on the first taste. I thought it was spoiled. Another taste and I thought Miracle Whip. What I finally determined was this is a light version of Miracle Whip. I personally dislike Miracle Whip, hence my reason for buying mayonnaise. They are not the same thing.
Please write or call the company and get out real stuff back. There are too many things changing in the world as it is. Some things are just good the way they are and don't need changed.
