I haven't got to that part of transaction yet though he only mentioned me his inventory (8x $50 Starbucks Gift Card)
Oh I see he have ran something like that in the past... Can I ask how can someone still get away even with escrow? Sorry I ask lots of questions please do answer me when its convenient to you.
I'm not exactly an expert on Starbucks and/or their policies regarding carding/cracking, but i know that most companies will disable giftcards once they find out they're carded, or stolen or cracked.
So let's say that either he has cracked them, (there's tools you can use online to do so), in which case your giftcard i guess could work fine, but it could also get disabled by starbucks out of the blue due to it being cracked.
Or he has carded them, in which case Starbucks will probably disable your giftcard as soon as the owner of the card reverses the credit card payment. So it might look like the cards work fine, but there's a good chance they'll stop working sooner rather than later.
Or he's totally legit, and there's nothing to worry about. I don't know. just be cautious or factor in the risk of them being carded.
