I'm trying to buy Tekken 7 off of him. Already paid for it and up until the payment he has been very quick to respond. Now after I have paid there's no communication at all, even though he seems to browse NeoGaf the whole time. It's been a few hours now and I know that isn't a long time yet, but he doesn't even reply if he received the money without problems. Like dude, don't offer goods for sale if you can't provide them or at least inform your buyers that there might be a delay.
I fucking hate myself for not checking the feedback list beforehand
Edit: In the end he came on through with the key. The whole process still left a sour taste in my mouth.
