Amazon has an option of refer a friend and gives as a code to give to our friend and the offer says your friend gets 100 rs gift card and if your friend buys something which is cost of more than 300rs then you will get 200rs gift card so I reffered my code to my three of close friend none of them got 100rs gitf card and one of my friend bougt a mobile phone cost 30k one friend bought headphone cost 2k one friend bought a cover cose 500 but I dint get any 200 rs gift card back so that thing is false in amazon
