There are two Bargaining magazines in Dead Rising 2 for the PS3, Xbox 360, and PC that will each make items at the pawn shop cost 10% less than normal. These are great to have when buying the expensive vehicles so you can save several hundred thousand dollars on each.
Check out the full Dead Rising 2 store map if you need help finding them.
Bargaining 1 – Right next to the hidden Zombrex in Bennie Jack’s BBQ Shack (A101) in Americana Casino. Go upstairs in Bennie Jack’s and go to the right. Climb up on the ledge and jump out to the hanging lights. Keep jumping to them until you get to a ledge where you’ll see the magazine. Grab the Zombrex here as well if you haven’t already.
Bargaining 2 – Above Speedy Expresso (F108) in the Food Court. Look to the left of the shop and you’ll see some vending machines you can climb up onto. Look to the right and you can jump on top of the building. Jump up and run to the other side of the building and you’ll see the magazine laying on the ground.
