There are some OK deals here, but my advice is to just get the Humble Bundle this week (though I can't imagine any CAG hasn't already jumped on that incredible deal) and then wait for Amazon to have its next sale on EA titles.
Amazon regularly has bundles that include most or all DLC for extremely low prices. For example, last year, they had a deal where Dragon Age Ultimate and Dragon Age II were bundled together for $9.99. There was another deal where Kingdoms of Amalur with all DLC was $9.99. And there were plenty of other packs of games for similarly low prices.
EA does a terrible job with promotions on Origin, but Amazon has always done them well. I'm hoping we'll one day see a Sims 3 bundle on Amazon that's actually worth the trouble. I'm also holding out on a good Battlefield 2 BC and Battlefield 3 bundle, since I know Amazon will likely beat anything Origin has to offer now.
