Title says it all... I am very reputable.
I disagree that you are "reputable" as you only have two people leave feedback on your trust, only one of which has actual "green" feedback on his profile. I am not saying that you are going to scam, only that you do not fit the definition as someone the community has confidence will not scam others.
Your price is also much too high. Someone could buy this same denomination gift card from gyft.com for only $2 more then what you are asking for and such transaction would carry essentially zero risk
