This was my favourite platform for buying stuff online before I started using Amazon for often.
Dont get wrong tho. I still use Flipkart for placing orders like phones, books, gifts, etc. The books there, cost really low, compared to Amazon or Snapdeal. And even the phones cost significantly lesser than other sites.
If we talk about the delivery, you usually get free delivery, and you receive the product within 2 weeks max.
I also ordered a gift for my mom on her birthday once. They only charge 30 rupees for that and it comes nicely packed with an option to write custom message. So, thats a plus point.
