Free Stuff in the Cereal Box

Cory opened the Honey Nut Cheerios this morning. There was a free book from The Spiderwick Chronicles in it - very small book, but still a book. Apparently I didn't pay enough attention when I bought the cereal because there are three different books being given away in the cereal, and I got the same one in both boxes I bought. First of all, I didn't know there were three different ones so I didn't know to look. Second, he told he me doesn't really like The Spiderwick Chronicles, so what difference does it make? Third, I went down and looked at the unopened box. While you can see a bit of the actual book through the front of the box, I don't know if I would have been able to tell the difference anyway.

My other option when I bought the cereal was to get a free trial membership in some online weight loss/health site. I guess I should have gone with that.

Do you pick your cereal boxes based on what free stuff is in there?
