Pay attention to the “Best By” versus “Use By” label. “Best By” is a suggestion from the chip overlords. “Use By” is for safety-sensitive foods (like dairy dips). Most chip bags just say “Best By.”
Here’s the real villain: light and oxygen. That clear window on the bag? It’s a double agent. Sunlight speeds up oil rancidity like a microwave for taste. Store chips in a cool, dark place. Your future self will thank you.

Why do chips even have dates? Two words: marketing psychology. Companies want you to panic-buy new bags. They know most people treat “Best By” as a death sentence. It’s brilliant, and a little evil.
Even the USDA says it’s fine to eat chips past their date—if they smell and look okay. Trust your nose. It’s smarter than any printed number.
