henry26 - I don't know about India, but in the United States, the best grocery stores are Walmart & Kroger. I prefer Kroger because of many factors. I love their atmosphere, product quality, services, low prices, and employees behavior. If you are a Kroger customer, then you can also have a chance to share your feedback at https://krogercomfeedback.com/ official site and win 50 fuel points for free.
