Every seller here has their own creative story on how they get their products. Sellers come and automatically think they're the most trust worthy people, unlike other sellers when in fact, they're the ones who should establish themselves first.  Nothing against op, just generalizing. In a community where 90% of the people are scammers, it should already be a norm that you can expect to be labeled a scammer until proven otherwise.

Since op is willing to escrow, at least it at least proves he's got the product he's selling and is willing to come through. No one here should be holding onto a gift card they buy for more than a day, even then is a stretch.

You can PM the people who bought it and get their feed back to see if their orders shipped.
