You are trying to say that the cards arent claimed via fraud. Then why are you selling it for that cheap?! You could just things from amazon with the money you have and sell it afterwards via local stores, internet etc, or just using it yourself
There's an old saying that goes like 'When something appears to be too good to be true, it usually is'. I can only think of gift cards obtained by frauds for such low prices. Or fraud otherwise. I think an acceptable discount on Amazon cards on these forums is about 10%-15%. Maybe 20% when you are Lucky, but not more than that. (Even then you have to be carefull who you buy from).
