Black Friday began on Thursday this year – in some cases before Thanksgiving dinner – in a move that big retailers suggest was a success. A record number of stores opened on Black Friday Eve, including Macy’s where 15,000 anxiously waited for the doors to open. The shopping marathon continued overnight into Friday morning with frenzied shoppers snapping up deals on big-ticket electronics and children’s toys. Several incidents of violence have been reported. Shop safely, friends.
