We see some pretty amazing deals but this one made me do a double take. Amazon is offering Portal 2 for only $34.99 and free shipping. Portal 2 normally sells for $59.99 and this offer is definitely limited so hop on over and give yourself something to do while PSN is down. And, for the time being at least, Amazon is offering $28 to trade in Portal 2 (this may not last but hey, for now it's their quote) so buy the game, play like a mad man for a week, and take it back to Amazon or GameStop and you may end up playing an incredible game for $10. How bout dem apples...
