Walmart is instituting a major change in the way it will handle Black Friday lines after the death of a worker last year. Instead of lining up outside of the store, creating a stampede for the best deals at 5 AM, most Walmart stores will remain open for 24 hours so that shoppers can enter the store in an orderly fashion and wait in the comfort of the florescent lights and 68 degree heat. So how will this change affect your quest for whatever notebooks and gadgets Walmart offers on Black Friday? Don’t worry; it’s going to be a lot more orderly and, thanks to coordination with several sources, safer.
