The few exceptions where buying in bulk makes sense
Because very little in this world is black and white (except for old-timey photos of your grandparents back when they loved one another), there are some situations where it's perfectly OK to buy food in bulk. Notice none of these situations are "you find a super-good deal to buy a case of perishable food you'll never be able to finish before it goes bad."
You have a huge freezer
"Buying meat frozen is fine," says Lempert. "Frozen foods, if packaged properly, will last a year." Check our handy chart for specifics, but it's definitely incumbent on you to store everything correctly. While food lasts "forever" in the freezer, it doesn't mean it'll taste good forever. Make sure you seal and package your meat correctly, and that you write the purchase date on it.
You live with a bunch of people/have a family of 25
Buying in bulk makes sense if you split it with a bunch of roommates or family members. Then you're getting the cost savings without overburdening yourself with a case of something like Cadbury Creme Eggs. We get it, Easter is extremely exciting.
You're about to have a huge party
"When it comes to large jars like salsa, mustard, and ketchup, for the most part it'll go bad unless you can use it all -- like if you're entertaining," Lempert says. "That's a great time to buy in bulk in those large sizes: if you're having 20 people over. Use it, but don't expect to have a storage space for it... or expect to use it up until it's wasted."
