In Scott Pilgrim vs. The World for PS3 and Xbox 360, Mobile has a secret house where you can purchase some decent items.
Toward the beginning of level 6 you’ll see Wallace and a few others standing by some trees. Right in the middle of them all you’ll see a white gap area. Walk into the gap in these trees and you’ll warp into Mobile’s house. Go into the door on the right and you’ll access his store.
