Myth: Buy everything in bulk
Think bigger is always better? You might want to think again. Check the unit prices before you buy: Items like cereal or frozen foods are sometimes cheaper in smaller quantities, according to Natasha Rachel Smith. Plus, you could waste a lot of food (and money!) if you don’t finish items before they spoil. To get the most bang for your buck, stick to healthy pantry staples or frozen goods that you often use, and make sure you can eat everything before it goes bad.
