Not sure how many do this but it doesn't hurt to ask. Next time you need Ground Beef and some other beef in on sale cheaper, take the package of meat to the meat departments counter and ask them to grind it up for you. I know the local Price Choppers do it, not sure who else.
Something I want to get back to because I think it saved me money is pay cash for my cars. For the longest time I bought cheap cars on cash and drove them until they died. Usually I was buying a car using cash every 2-3 years and Most always paid less in repairs and initial purchase than I do now in payments and repairs.
