I have purchased many product from amazon till date and found that their product genuinity, Seller genuinity, price and delivery are up to the mark.For customer satisfaction they always proved best with proper information and attention to your quries.Thier communication system for query related to product, packaging, refund and delivery are too best.Even customer care executive will understand quires first and then appropriate reply with fact and knowledge are given.Website usability, ease of search and purchase, discounts given is very impressive.
