So I am customer who has purchased things from amazon.com, amazon.in, flipkart, and snapdeal. What can I say about Amazon they are the best in all departments. Flipkart is good, but Snapdeal sucks at delivery/shipping.
I purchased a laptop from Snapdeal recently, at buying screen/page it displayed that product will be shipped in 4-5 days, which is fine. Got an email that product will be shipped after a delay of 3 days, so that makes it 8 days, but after that no communication/emails. It has been 11 days after ordering the product, but still it is not shipped. Called up customer care and they are telling system issue regarding info and emails, but they say in 48 hours it will shipped or order will be cancelled. So after 11 - 12 days if they inform me this, when I call them, I think it is fair to say that their Service and support sucks.
Also, I had bought a Chimney earlier from Snapdeal, which I got in 10-12 days. The product did not have much description/details on Snapdeal, but when I arrived I realized that it did not meet features as in international products from the same vendor and model. Also the Chimney had scratches. I have posted a review for the same on Snapdeal, but they have omitted the Shipping/Delivery review, so I do not think that this company believes much in ethical behavior.
