New And Improved

I saw this sign at the post office the other day. Unfortunately, I did not have a marker with me to correct it. So here is a reminder. There is no such thing as "new and improved." Something can be new, in which case it has not been improved. Or it can be improved, which means it is not new. Of course, it can be newly improved. But absolutely, under no circumstances, can something be new and improved. Please correct your sign.
