Exorbitant

You mean my avatar picture? Mine is unopened, but based on experiences of other grain products, the cereal will be VERY stale and bland. Especially, after 20 years.
Did you keep yours in a pressure sealed container? That might help. My box just hangs out in the back of the pantry with me yelling at anyone that touches it.
While visiting Orlando back in 1993, I paid a visit to a place called Gatorland. I bought a can of gator meat there and never opened it. I threw a party on the night when Nebraska played Florida. I set the can on my TV for the fun of it that night. I still have that unopened can.
