I have been a long term user of Amazon.in and so far I have had a great experience.
The whole shopping experience is well organised, the products are very well categoriezed time saving and very convienient. Yes you do not get any touch and feel experience, however shopping from the comfort of your living room is unmatchable. If in doubt you may always read honest reviews by previous customers.
All products delivered were original and price worthy. Status of order can be tracked from order to delivery.
Lastly they send you a feedback post delivery, you may express your experience. I never had any complaints against them.
