Walmart's Black Friday shenanigans are now more insane than ever. Beginning Thanksgiving night and ending Cyber Monday morning, the big-box retailer's five-day sale extravaganza has been split into three parts: a 6 p.m. Thanksgiving Thursday doorbuster, an 8 p.m. doorbuster on the same day, and the traditional Friday sale that begins at 6 a.m., two hours earlier than last year. This doesn't even count the sales that extend to Cyber Monday, Dec. 1, which haven't been announced yet. To stay competitive, Walmart even told its store managers to match prices with Amazon [1]. You bet that, like Target [2] and Best Buy [3], there is a lot of tech up for grabs. Here is the best of it.
