When I started online shopping, I’m using the Amazon.com. Here is a wide range of products and services. It gives very good customer service. It’s product quality is very nice like grocery items, mobile gadgets, etc. Amazon always delivered it’s all order on time. It had not any issues with the refund of any item like other shopping sites. All other shopping apps have to learn from Amazon.com. I’m never feel worry about that the product reliability. I’m always recommend all people to use amazon as shopping cart.
