Always loved the snatch-a-pak's as a kid -- my grandmother had those for when we slept over at her house. I seem to remember there were ones that always went first and one that always ended up being last (probably All Bran). Never did use them as a bowl but thought that was neat.
I ended up buying two of each of the Cereal Boxes so I could open one set and keep the other sealed (like I need to have more saved stuff! DOH!). Really wish they had done new art all the way around the boxes though -- THAT would have been cool.
Mine didn't ship until yesterday though, so I probably won't get 'em until next week. Dang. I ordered them as soon as they were on the Topps site too. Sigh.
