Shelf Life of your Herbs and Spices

I found this in a McCormick's ad and wanted to share it with everyone. This is a short and simple list of the Shelf Life for your herbs and spices.

Spices, ground - 2-3 years shelf life
Spices, whole - 3-4 years shelf life
Seasoning Blends - 1-2 years shelf life
Herbs - 1-3 years shelf life
Extracts - 4 years shelf life, except pure vanilla which lasts indefinitely

I think I'll clean out my cabinets and buy fresh. I'm sure I have at least a few that need to be replaced.
