Miss this at your own mental risk.
Lewie's just sent over word that Halo: Reach is now available on Play-Asia for £15/$23.
Worth noting that this is the Asia version, but it is compatible with PAL Xbox 360s and has English VOs and subs.
Only differences are the packaging and that you probably won't able to trade it in.
If there's one thing you do now, it's that you buy this game on the cheap before stock runs out. GO!
