DealNews Black Friday has posted its coverage of the Best Buy Black Friday Ad. (If you prefer, you can also view it on the Best Buy website.) A selection of doorbuster deals start at 5 pm local time on Thanksgiving and run through 1 am on Black Friday morning. Stores then re-open at 8 am on Black Friday for another round of doorbusters. (Tickets will be handed out up to two hours in advance for both these openings.) Many of these deals will also be available online. Notables: Our Black Friday section features category browsing so that you can compare, say, all Black Friday electronics deals from all stores. Or, download the DealNews Black Friday App for iOS or Android to view these Black Friday ads on your smartphone or other mobile devices.
