no offense, but people can buy multiple amazon cards a discount rate on a legit place.
places like gyft, or purse.io. It may not be staggering with 65%, but its 30% which seems without headache.
Or localbitcoins. I see people buying Amazon gift cards (wit photo of card and receipt) for twice the going rate of BTC. He could be selling bitcoins for Amazon GC @ $600 then buying things with them on here and he would make %15 on every order and it wouldn't be a scam...i think.
