I'm trying to buy a gift code of Planescape Torment so I can send it to someone. When trying to purchase, I am only given the option to gift it to them via GOG's email system since I already own the game, but I'd really rather send the email myself. Is there any way I can just purchase it as a code?

Ah, wasn't sure if their email would be a code or a link-to-redeem. It is the former. Thanks!

You'll find all your purchased gift codes, their status and what e-mail account they were send to under "Account" -> "Gifts". Oddly enough, I'm pretty sure there was resend option before site upgrade (downgrade imho) but I'm not seeing it now...

Actually, it's both. Anyone with the link can click it to see what's included, and can then redeem the code. Apparently you can now also choose which games to redeem from a code that contains multiple games.

Example:

lulz at code-dropping free game. :) How many scrambled for it?

It's not the first time I do that either, but it's been a while :-)
