I, too, LOVE Kellogg's Croutettes and the reason it is hard to find is because they have changed the name to: Kellogg's Stuffing Mix.
You can order it here by the case:

Or you can go to this link :

http://www2.kelloggs.com/product/wheretobuy.aspx

and type in your zip code and on the drop down menu choose - "Stuffing Mix" and it will give you the stores nearest you that carry it.
I found 7 stores in Charleston, SC.
It WILL be a wonderful Thanksgiving!!!
