the_voivod: Accidentally added a gift of FTL to my account and now told I can't have it changed to a gift because it was free. Bleh! Not sure why, since it gives you the option of sending it as a gift when you checkout (which I obviously forgot to do).
Shendue: Actually, it didn't. The gift option was grayed out and not selectable on freebies. You only got a code if you already owned the game.
I had the same thing. I scored a crit on Broken Age and the gift box was greyed out.
Maybe it has something to do with the fact that I was browsing on a smartphone at the time?
I wanted to change this to a gift since I already have the game (I was a kickstarter backer) so I wrote GOG an email and they said they couldn't change freebies to a gift code
I'm perfectly ok with that though; it was awesome enough that GOG just gave away all these games!
A gift is a gift; besides, at least now I have a GOG version, which is always preferred :)
