Store coffee in the freezer. It keeps the coffee fresh from the first to last cup. Put enough coffee into small snack size zip lock bags to make 8 cups, then store them in the freezer. It's a little extra work when you first do it, but saves time when you're in a hurry. When you're down to the last couple of bags you know it's time to buy more.

If you run out of coffee filters and are too lazy to run to the store, try using a paper towel instead.
