Yes flipkart is good, and also you get fake products on the site. Don’t get confused, before placing the purchase order you have to confirm with the seller and only go for the order is the seller has flipkart advantage tag on it. Many other sellers on flipkart sell fake products under the name of huge brands. So before purchase you have to be careful.
And replacement of flipkart is not as easy as amazon. For an electronic item getting the replacement or refund is very difficult. Still if you shop with awareness you can hey good deals with original products on flipkart.
