The difference acc. To me between snapdeal.com and other such websites is the decent customer care service tha snapdeal offers. I had some issues with them regarding the order and delivery of a product. Apparently, their vendor ran out of stock while they had already taken the order from me and the payment was processed too. But since i needed the product, they still managed to provide it to me albeit pretty late than what was expected. Surely, i had to pursue this matter with them rather diligently, but they stayed in touch and fulfilled their commitment.
I have bought nearly 6-7 deals from them, other than the one i mentioned, and those have been pretty satisfying. Decent delivery time, good customer care (cc reps are well mannered. And actually willing to help), most of all the will to resolve the issue & not just ignore the problem to make money at the cost of customer, is what i liked most about them.
Certainly, worth a try.
