Summarize this article:

Don't do it. Just don't. There are hidden costs that can deter you from financial success. You're paying for the service, for the location, the effort of cooking, and the establishment's profit. You don't know what goes into it, either, so you can't control the amount of sodium, sugar, and other nutrition factors the way you can when you're cooking at home. Buying in bulk doesn't mean you have to buy a lot of it. The “bulk” aspect of it only refers to how a store presents it, not how much you need to buy. Buying only as much as you need ensures you will keep your pantry items fresh, wholesome, and less likely to wind up in the trash. Because it is whole food, you are packing your family's diet with nutrition. Take advantage of the discount you'll receive due to the lack of packaging, labeling, or advertising. Re-organizing your cupboards to better handle your bulk items. Purchasing some airtight containers will be helpful in the organization of your pantry. Buying less and eating less is an easy way to save money. Cutting back on snacks is a great way to stop overeating and, considering snacks can oftentimes be prepackaged food, is also the most expensive items on a grocery list. You don't need pine nuts for pesto. You can easily substitute cheaper and healthier walnuts.

If you don't like plain water, splash a little juice in it or throw a fresh slice of fruit in it. This will save on calories as well as money. Take inventory and plan your meals in advance. Doing so will help eliminate last minute runs to the store, where you will inevitable spend money you could have saved. It will also reduce the stress and chaos that can occur during mealtimes.
