Having recently picked up a couple of bargains today, I think a thread detailing how cheaply we have picked up old games may be a good idea, mostly for bragging rights as links may not be necessary/in existence:
Gamestation PC Preowned:
Gunman Chronicles - 49p Mechwarrior 4 + Black Knight Expansion + unexpected copy of Motocross Madness 2 - £3.99
CEX Walsall Xbox: Crimson Skies: High Road to Revenge, Ninja Gaiden & Dead or Alive Ultimate - £3.00 each
