Amazon.in is the best app/website for online shopping. it contains very large variety of products, as you seen in tv add it has crores of products. When I search any product it always gives me options of related product to choose better and cheap product. and you can also compare prices of the products.
Amazon.in has fastest delivery options, as if you need product very urgent. they can deliver it next business day. the another thing which I loved it is its return policy. if you dont like the product you purchase, you can return it very simply., with in mention days. I strongly recommend this website/app for online shopping.
