Don't believe the packaging.
You buy cookies in a supermarket. It says "BEST HOME MADE COOKIES IN THE WORLD".
They are not home made and they are not the best in the world. Your bubby makes much better cookies than those.
The package of the lulav or esrog says "Mehudar Alpeh Aleph". You might well find out when you bring it to a Rav that they are either pasul or at least not mehudar.
Beware.
