Human: What are the best ways to save money on my grocery bills? Assistant: 

1. Make a list and stick to it. This will help you avoid impulse buying and make sure that you only buy what you need.
2. Compare prices between stores. Look for deals, discounts and coupons online before making your shopping trip.
3. Buy in bulk when possible. Buying in bulk can often lead to lower costs per unit.
4. Take advantage of store loyalty programs or rewards. Many stores offer special discounts or other benefits for customers who sign up for their loyalty program.
5. Avoid pre-cut produce. Pre-cut produce is often more expensive than whole fruits and vegetables because they require extra packaging.
6. Shop at discount grocers. Discount groceries may have slightly higher prices but can be worth it if you're looking to save money.
