Thanks for the Kellogg's heads up.
I was actually in the mood for some Kelloggs Pop Tarts (Frosted Brown Sugar, Yumm...) this morning and had gone searching the local Safeway when I noticed a single box of Pastry Swirls with the AA miles certificate. The thought of another free 100 miles was almost enought to tempt me away from my quest for Pop Tarts when I noticed the expiration date on the box was March 10, 2002. Yech.
Needless to say, I bought the 8 pack of Pop Tarts and did without the miles.
