I have, but not for the grandchildren.
A few months ago I bought this spaghetti sauce that didn't have a huge amount of green bits so I was like SCORE, and bought two more jars. I finally ran out and when I bought it again they had changed it in those few months and now it's full of chunky bits of tomatoes and onions (which is great, i'm okay with that part) and so many green things.
There was no point to this story.
