I got in on the deal. I know multi-grain, honey nut, peanut butter, reeses puffs and Dulce de leche cheerios are all included. When you buy 5 boxes,you will get a $5 Catalina.
On the general mills site, there are Qs for .75/1 multi grain cheerios. If you printed 5 Qs, they would all be free. I got 2 boxes, and 3 boxes of others using a $1/3 q. Making it $2.50 for 5 boxes of cereal!
P.s if you haven't tried them yet, the peanut butter cheerios are delicious. My 2- year old is sitting here eating some right now.
