Amazon is the biggest online trading company and my faviorite. The most trusted site in online shopping is amazon as whichever product I had ordered were 100% genuine.
The company also provides fastest delivery system and also lets you know where does your order has reached and when it will be reached finally.
Also it has wide range of payment options i.e.
-Debit card
-Master Card
-Online payment
-Cash on Delivery
Amazon has also very nice after sales service and cash back value option.I prefer to always use amazon for online purchase.
