Watch Your Expiration Dates
Whether the expiration date is already printed on the package or you sort it out with an online tool like StillTasty, keep that date in mind. You don't want to expend all of that energy bargain hunting only to have your bulk items go bad in a lonely corner of the pantry, fridge, or freezer!
Organize your bulk items so goods that expire sooner are closer to the front of the freezer or pantry for easier access. When it's time to get cooking, you'll be more likely to use what you can easily see, which will help you reduce the amount of food that goes to waste.
Keeping an eye on those expiration dates isn't the only way to prevent your bulk food from spoiling. Making sure that you store things properly can go a long way in making those purchases last.
