Buying Xbox DLC

Halo 3: Mythic Map Pack II (Longshore, Heretic, Citadel)
Modern Warfare 2 Stimulus Package

I will be paying via PayPal. Post how much you want for them here.
The way I will be doing this is that you must already have the DLC downloaded on one of your GT's. I will recover the GT and download the DLC onto my console, which costs you nothing! I am paying back with PayPal, so you are basically getting paid for something you've already paid for and downloaded.
