How to purchase 2 or 4 packs as a gift.

You can only buy these packs if you don't have the game already in your library. Also, if you don't have it in your library, you can buy these packs, but one copy will be added in your library, want it or not. :/

can only buy from your alt account then, which will redeem 1copy upon the purchase and give you the spare in gift form.

edit: lucky beat me ^^

your own risk, not sure it still working

Thanks for responding guys. I just ended up buying 2 gifts for portal 2. I was going to give them to my friends, who I am trying to get into gaming since I think Portal 2 is a fun co op game that has a low point of entry. So even if someone does not play videogames, its reasonably easy to play and control, while still being tons of fun for the co op and puzzle aspect.
