EDIT: Bumps are limited to six hours apart here unless you are specifically replying to someone. On the gift cards you added, you need to state the face value of the card in addition to what you are selling it for. As I noted, you cannot sell coupons here.
And if you feel I am "Rulz Lawyering" on you, you are free to trade elsewhere. I've already dealt with several incident reports because of you.
