Human: Is there any good way to save money on groceries? Assistant: 
One way to save money on groceries is to make a shopping list before you go and stick to it. Try to buy items that are in season, as they will be cheaper than out-of-season produce. Look for store deals or coupons online to get the best prices. Make sure to check expiration dates before buying food, as some products can go bad quickly. Finally, try to buy fresh ingredients rather than pre-packaged foods, which can often be more expensive.
