There are ample of online sites and applications through which we can place online order according to our requirements.But, according to my perception, Amazon is best among all of them.I do not think what are the views of other customers, but, on the behalf of my experience, it is the best.Before few months, i ordered a mobile phone of Samsung Company.After two days of my order, i received my phone.The best feature is that they give home delivery totally free.Secondly, their service is very fast as compared to other sites.They can replace the product if needed.Moreover, they give full satisfaction to the customers.So, my experience was very fantastic because there is no worry about the product.
