Right now, Amazon.com is offering up some fairly substantial savings on a large number of games. Many of these games (not all) can be activated through either Steam or Origin.

There are games like Batman: Arkham Origins for $17 (USD). Maybe Scribblenauts Unmased for just $10 is more your style. Perhaps a two pack of both XCOM: Enemy Unknown and XCOM: Enemy Within for just $15?

There are plenty of additional titles there including Battlefield 4, Hitman: Absolution, Tomb Raider, Sleeping Dogs, Final Fantasy XIV: A Realm Reborn, Planet Horse, and more.

You can see all of the deals (and there are apparently 94 of them in total) over at Amazon.
