How about this...

I have Grand Theft Auto (san Andreas) for the PS2.

Send me a fiver to cover postage and a bacon batch and I will post it out to you.

Used it once and i mean once (same as the ps2 that is sitting in a box for the last two years lol), still in box, unmarked disc and instruction manual. Just check that is the one he wants as there are a few I think.

PM me your address and I will post it out tomorrow and trust you to send me my lunch money.
