Also available is Caramel Crunch which is meant to be like Samoas/Caramel deLites. Both are sweetened corn-based cereals.
The limited-edition cereals starting rolling out in early January and should be widely-available at this point (including online). You can find them in 11-oz boxes for about $3 a box as well as in "Family Size" 18.5-oz boxes for around $4 (may vary).
