I actually had a similar thing with another member buying codes from me today. He bought the codes, and I told him i wouldn't be home for a couple hours. He was ok with that, and paid right away.
Well I wasn't able to go home right after work, and it ended up being closer to 5-6 hours. He send me a friendly reminder PM, I sent him the codes right when I got home, and all was well with the world.
Pretty simple with a bit of patience...
