Hmmm, I wonder if there are many cereal boxes still out there with the certs, or if Kellogg's has moved on to something else now.

Also, are the offers mutually exclusive? The wording says one cert per Aadvantage account, but since the certs are different, does that mean one of each per account, or would using the offer with the 300-mile mean you can't send in another with the 200-mile?

This might be useful as a topping-off move for me.
