PSA: Riot has THREE free champions / skins for everyone to obtain!

So a lot of us know about this already, but a lot of us also don't know about it at all. I'm talking about the three free skins and champions Riot has been giving away for free for pretty much forever. What are the skins/champs and how do you get them? I think these might be NA only, so just a heads up. (enter the codes in the LoL game client, there's a tab for it in the store.)

Dreadknight Garen: Follow League of Legends on Twitter. https://twitter.com/LeagueOfLegends/status/447126845276696576 (currently on sale too, but it's free here!)

Riot Girl Tristana: "Like" League of Legends on Facebook. https://www.facebook.com/leagueoflegends Just click the "Riot Girl Tristana" tab after "Liking" the page. (seems available to all countries)

Unchained Alistar: Subscribe to League of Legends Youtube channel. https://www.youtube.com/channel/UC2t5bjwHdUX4vM2g8TRDq5g I can't seem to post a direct link to the channel page, it just turns it into this video. Click the title to be redirected to Youtube.

I hope you all enjoy your free skins / champs!

Note: If you don't have the champion, the code will give it to you as well.
