Amazon is having a major sale atm - a "Digital Game Mayhem"
Some goodsorts over at NeoGaf have compiled a list of sale items
. They also have the item sale periods (what manner of strange magicks they used to obtain this information, I have no idea, but I sure am thankful for it).
Some interesting deals include:
Batman Arkham GOTY Pack: $11.49
Borderlands 1 + 2: $19.99
Dark Souls: Prepare to Die Edition: $7.50
LEGO Lord of the Rings: $7.49
Mass Effect 3: $5.99; Digital Deluxe Edition: $8.99
Sid Meier's Civilization V: $7.49; Gold Edition: $12.49
Tomb Raider: $19.99
+Many, many more.
Already got Mark of the Ninja for $3.74. Got my eye on Dark Souls, Metro 2033, and Tomb Raider.
Courtesy of his venerableness, Sir Sabre for alerting me to this development.
