Hi, I want to share with you how i made $40 yesterday with amazon... So everything started when a friend had a problem with his gopro (recently bought on amazon), he used the amazon chat and asked for information because it was a problem not caused by himself. They said that there were 3 ways of proceeding, the first two involved a sostitution of the product, but the third way was interesting... they offered a 15% refund on the price of the product. My friend accepted the 15% refund (that is $40 because the price of the gopro was something like $250) and then he asked the gopro customer service and they changed for free his gopro (because it really had a problem). Then he told me (i've also bought a gopro in the same period of him on amazon) this story and we thinked: what will happen if I contact the amazon customer service saying that i had the same problem of my friend, in order to get $40. Well we tried, everything went fine and i got $40 =).
