One way you can save money is to make a plan, and stick to it. For example, let’s say you plan to go out to eat once a week. Stick to the plan, and you won’t spend money going out to dinner. This is similar to making a budget, but different. A budget is deciding how much you want to spend. A plan, on the other hand, is more like how often and where you want to spend money.
One of the best ways to save money is to do things yourself.
A lot of food products will up their prices for the sake of convenience. For example, buying a whole chicken as opposed to pre-cut chicken parts will be significantly cheaper. (Anderson Cooper, see first link)
We get into the habit of making everything disposable and convenient. However, it is wasting money. Why buy bottled water when you can go to the sink or fridge and fill up a glass? Why buy apples cut up when you can just buy apples and cut them? If you put yourself in money-saving mode, you will be surprised how many things you can save on. You just have to stop and think before you buy.
