Hi.my name is tarun
Amzon is worlds largest online store.You can get anything you want in that moment at this store.
Product quality of amazon assured products is good but the some products are local and hence they aare not assured by amazon.
Delivery time is about a week.But the main disadvantage of using amazon is that they can not deliver at some places.Mainly their delivery areas are metropolitan cities like Delhi, Bangelore, Gurgaon, etc.
There is a simplified user experience for users on their app called amazon.You can download it from play store.
Amazon is much reliable as they have to maintain their class in the market hence they have to be best.
Thank you
