Answer:
K mart wants the same $399.99 for the PS3 32- GB Move Bundle and the same $299.99 for the 160 GB PS3 Game console. They also have some of the PS3 120 GB models left that are still selling for $299.99 in spite of a smaller harddrive.
The Sony PS3 is not cheaper at one store over another by enough to make it worth looking or driving around over because they do not have a high markup. The only deals can come in Bundles that the stores make up adding games and accessories for reduced prices. Right now Sony is making the deal with the 320 GB PS3 + 99.95 move bundle for a best PS3 price ever.
