JMich: Single code. Redeeming said code adds to your account any games you do not currently own while leaving the owned ones to the code for later redemption.

Rhineland: That is meh. I'd prefer to get multiple codes as this would give the possibility to split a bundle (= codes for more than one person).

SandyKoala: So, say I have three games that I got back when the Pot of Gold Irish sale was on a few months ago, and I already own them, I can't just gift one game to one person, and then gift 2 to another. All three have to be gifted to one person?

Rhineland: Pretty sophisticated for trading with titles that are just worth a few dollars, but – sadly enough – it seems to be neccessary on those days. :(

Well, what titles are you interested in that are worth about 10 USD? I have no problem with sending you some codes in the first place as I don't think you are a scammer. When purchasing a game, can I just pick "Send as a gift" and enter my own email adress in order to get a code (which I then can give to anyone else)?

JMich: Support may be willing to split a gift code, but that is not a certainty. You can always contact them.
JMich: Yes, unless one of the two already has some of those games.

Grargar: If you are still interested in the trade, you could send me giftcodes through PM for Sniper Elite: Berlin 1945, Earth 2140 and Earth 2150, which currently cost a total of $10. In return, I will send you the giftcodes for Baldur's Gate 1+2, Planescape Torment and Neverwinter Nights 2. I will also send them individually, so you can decide for yourself what to do with each of them.
