Stretching out the grocery budget can help one discover little tricks. For example, I love coffee but cheap brands doesn't satisfy my tastes so this means I pay more. One tight budget months, I can stretch out the coffee supply by making a regular pot. I leave the grounds in the holder instead of throwing them away. Next time I make a pot, I add only half the amount of fresh grounds to the holder.
The second pot, to my tastebuds, tastes just as good as the first pot did. However, let's do the math: If you make one pot of a coffee every day, and use the above method, then you would be able to make 6 12-cup pots of coffee using the same amount of grounds that would typically make 4-1/2 pots.
