Last month I saw an advertisement about GoIbibo referral scheme through mobile contacts.
I installed Ibibo app on my mobile and send all my contacts to download on their mobile app.
As most of my friends travel regularly and book hotels, and they are doing regular booking, which giving me Rs 50 cash reward every time, last week I earned around Rs 4, 000. Which I used for my Hotel booking for free of cost.
This is a great referral scheme, because with out any hard work I am getting free referral reward every time.
If you are having a huge contacts on your mobile and they are booking hotels then this is the right app for you.
