I've got got a code for Borderlands, left over from a 4-pack, and a promo code for Lara Croft and the Guardian of Light XBLA for sale. Lara still qualifies for the free points for the Summer of Arcade if you bought some of the other games.
£7 for Borderlands
£9 for Lara
or £15 for both.
Also, I'll consider trades, in particular I am looking for (preferably 360 versions):
Super Street Fighter IV
Prince of Persia: The Forgotten Sands
Also, on the PS3:
3D Dot Game Heroes
Payment via paypal gift, and I'll PM you the code.
