Went into my local blockbusters and got got a few tips for you PS3 owners, or anyone looking to get a few extra quid off anything instore!
At the moment you can get the ace Oblivion on PS3 for 9.99 when you trade in ANY PS3 game,
Yes, Genji, NHL, NBA etc that you can get easily for £17!!! hence making it only £27 for Oblivion. I myself did this off by trading in NHL. Other stores like game aren't accepting these titles in their offers.
You can also get £30 off ANY PS3 game from trading in any of the above, which puts most of them down to 9.99 anyway.
EVEN BETTER.. if you dont have a PS3 or dont want another PS3 game then ALL PS3 games at the moment have £26 trade in value! so if you took in nhl, genji and nba, which cost me £53, you will get £78 worth of trade on anything instore.
I'd recommend checking with your local store first but i found all this out on saturday, i did the Oblivion offer with NHL and traded NBA in for £26 credit.
