Some of my favorites:
4. Try making your own coffee syrups and coffee creamers to help save on your coffee expenses.
7. Start keeping a price book to cash in on the best deals (you can download a free one here).
19. Make your own mixes instead of buying them.
34. Buy and prepare whole chickens instead of buying chicken breasts as a meal or shred this meat for your casseroles.
