Spices can be very expensive, here's an alternative, make your own pumpkin pie spice!
1/4 cup ground cinnamon
2 Tbsp ground ginger
2 tsp ground cloves
1 tsp ground nutmeg (see note)
1/2 tsp ground cardamom (optional)
Combine all ingredients for desired mix and blend well. Store in a small, airtight container. Feel free to experiment with amounts to get a blend that works for you.
If using freshly ground nutmeg, you might want to cut back a little bit because the flavor can be quite strong. Since you're going to be storing the mix anyway, it is not crucial to use freshly ground here.
