Visit the Store Before Hand
Learn the lay of the land. Know your way around the store, through the aisles, even visualize short cuts around the store . You might not know where sales will specifically be set up, but based off your previous Black Friday experience, you can figure out where certain key items will be. If your stop is the mall, then pin point the stores you want to visit and figure the quickest way to get to them and where you should park.
