You could pick up Mass Effect for $2.49, or Far Cry 3 for $7.48. EA's Mega Sale on Origin is actually properly mega with a tremendous range of games and DLC on-sale. Plenty of games are discounted by up to 75%.
It's a grand mix of super cheap old games, like Theme Hospital for $2.49 or Wing Commander IV for $2.49, and games that were released this year — such as Titanfall which has dropped from $59.99 to $29.99.
There are a lot of games on sale here, including some of Ubisoft's titles which are also available on Origin.
There are 49 Battlefield products on sale alone, which is pretty mind boggling. How are there even 49 Battlefield things in the store to begin with?
