Hi friends, We all know about Amazon the largest E commerce site . I recently purchased a GIFT CARD to present to my friend on his birthday. It was shown$5 I paid for it online. I send that card to my friend but when he tried to redeem it, it says invalid. As I complain to them, they said that can only be redeemed in amazon.com, which is international market. They also refused to refund my money. Its my worst experience with Amazon. But in shopping purpose I never experienced any problem.
