I was just looking on the shopto website for some cheap PS3 games when I come accross this. Now I don't own RDR any more but am buying it back when the new DLC arrives. But I just bought a the code now for 1p. The code is showing up in my account. This is not a PSN code but a unlock code for ingame. Am guessing it will be a unlock code they gave to people when they pre ordered the game so not bad for a penny.
Not sure what the DLC is lol.
