Amazon have TV Superstars at £9.56 each (two for £19.12.)
Not such a bargain, until you take into account the current £10 discount when buying two selected move games.
2 copies of the game for £19.12 - £10 = £9.12... bargain!
Now the interesting part... ASDA just game me £12 for EACH copy.
So trade one, keep one, and you've effectively got a free game.
Or, trade them both and turn £9 cash into £24 credit at ASDA. Seems good to me.
(For anyone interested, ASDA put the game out on the shelves marked as pre-owned for £20, with Amazon's plastic wrap still on it!)
