My apologies for the late notice, but I didn't get a chance to post this earlier.

Albertson's currently has a Buy 4 Participating GM Cereals, get $6 off instantly.

The smaller boxes of cereal are priced at $2.99, which makes them $1.49 after discount.

There are tons of GM cereal coupons out there {coupons.com, eatbetteramerica.com}. There's also a $1 Kix coupon on kixcereal.com

So far I've bought:
Kix Cereal {regular, 8.7oz}
Cinnamon Toast Crunch {w/Shrek toy, used $0.55/1 from coupons.com & EBA - "doubles" to $1, 12.8 oz}
Cheerios {regular, used $0.55/1 from coupons.com & EBA - "doubles" to $1}
Trix Swirls {14.8 oz, used $1 homemailer - this was $0.99 AC, there's a smaller size with a Shrek toy that should be $0.49}

It seems like it's mostly "kiddie" cereal that are included - I haven't seen tags on "adult" cereals like Fiber One.

Anyways, hope this helps somebody!
