Is Bulk Buying Always Worth It?
Warehouse clubs and bulk retailers promote large packaging sizes as the ultimate money-saving hack. While unit costs are almost always lower upfront, unconsumed waste, limited storage space, and food spoilage frequently wipe out those initial savings. This hidden financial leak is known as "phantom savings"—money you think you saved but actually threw away in the trash.
