From foreign news articles it does seem like flipkart & amazon are the big deal which is why I find it confusing why in india snapdeal is a bigger deal.
Flipkart is technically more impressive than Snapdeal. (Flash sales/in-house hardware, etc). It has it's own brand similar to Amazon basics - DigiFlip, some of which are of decent quality - cables, chargers, etc.
we have done all the price comparison and we have found that deals,coupons etc are not worth the time. I just want a site that I can go to and be somewhat sure that I am getting a good price.
Flipkart is fantastic for that. I have never ever found a product on flipkart that is cheaper elsewhere and I can also see my other options for similar products on the same site.
If I am being adventurous, I browse ebay where I get good deals.
