I have ordered a number of times on Snapdeal, shopping included hidesign bag, books, shaving material etc. I primarily order from snapdeal for the great prices, got the Hidesign bag at 50% discount which was awesome, but they have very limited quantity of stock on such discounts. If you are sure of the purchase then just order especially in cases where they offer bigger discounts/special discounts.
Secondly, I am always impressed with the packing, one of the books which I had recently ordered - the book was wrapped in a bubble wrap in a neat box. Always great to see the packing.
Products: am quite happy that in all the cases that I have ordered on Snapdeal I have got authentic products, which is great.
Delivery times, in majority of the case the delivery is pretty quick three to four working days, have experienced a delay once but got the product by next week. I would totally recommend the site for the great prices offered by Snapdeal(but as a rule I always compare the prices at other usual sites before ordering)
