Human: What is the best way to save money while grocery shopping? Assistant: 
The best way to save money while grocery shopping is to plan ahead and make a budget. Try to create a shopping list before you go to the store, so you don’t impulse buy items you don’t need. Comparison shop for the best prices and look for deals and discounts, such as coupons or store loyalty programs. Avoid purchasing pre-packaged and processed foods, instead buy whole foods like fresh produce and meats that are usually cheaper. Consider buying generic when you can and don’t be fooled by large sizes or “family packs” which are often more expensive per unit.
