I am using Amazon app from more than 6 months and did shopping for many items it is really amazing to do shopping on your finger tip. The best part for this app while shopping is Filter where we can apply filter according to our need.
Right now amazon having product of your daily need also with best market price. I feel secure while shopping with Amazon. It has multiple option to do payments either you have debit/credit card or not. If no bank also then you can use Cash on Delivery.
