I usually buy things online but not satisfied with any shopping site. Different sites promise timely delivery but half of the time they didn’t deliver their products on time.
For the first time, I ordered few products from Amazon and they promised me to deliver them in 4-5 days as others do.
But I felt happy and pleased when they delivered them in only 2 days.
The major and important role of online shopping sites is to deliver their products on time and for the same reason I rate Amazon No. 1 shopping site.
