So just a quick question. I bought a game and got my code for a free interplay game. Can I save this code for future Interplay titles? Or will I have to use it now?
Lots of good titles on there now... I'm just patient and can wait for something down the line.

I see... then I should probably use it.

So how long after your order summary arrives after your first game purchase before you get sent a code for the free game download?
Never mind. Didn't realize I used one of my email aliases to register. Guess I'll have to
order another game to get the free code using my other address...

Showed up in my inbox at the same time as my receipt, personally.

so does this mean that I missed out? I purchased the game while the promotion was still ongoing (I clicked through from the promotion's page) AFAIK but, I haven't received any code. :(
What, if anything, can I do now?

I have the same problem. I emailed support and no one is helping.
