Are sales down for Oreo cookies?

They have so many flavors to choose from.They also note that a new flavor is a limited edition.Seems like it would cost more to make all the varieties than to have one good original one.

The newest one is a Selena Gomez type that is cinnamon.Even Post Malone had.a cookie with his name on it.Chocolate covered pretzel and S'more among others.

If I am splurging on a cookie just give me an original.
