I have been using online shopping from last 2-3 years as these online shopping trends got popular. I use to shop with Flipkart but after Amazon started their service in india I was too happy to take service from them.
Shopping with Amazon was exciting till the time I taken their service. I dont know how Amazon.com is doing in USA but in India, Amazon.in service is really poor.
No doubt they have plenty of sellers and product(off-course coz of their BIG Name) but they need to improve their logistic services.
I really got Frustrated of waiting some time after order any product coz their delivery time is too much.
Also, if you ordering 4 product they may reach you at 4 different date.
All in all.not bad .but not good too.
