Flipkart is a excellent online app which provides door step delivery. I found it better than Amazon as sometimes Amazon sends fake products but I have not experienced flipkart’s fraud yet. It has many options of products than Amazon and with ratings. It has cash on delivery method available while at amazon cash on delivery method is only available for amazon prime members. I will suggest you to see for your product on flipkart also which you are searching on other online shopping app.
Thank you.
