We're less than a week away from Black Friday, but bargains are already starting to explode. Here are five deals for as much as 77% off top brands from Amazon and Arlo to Hisense and Samsung.

The bigger-screen devices are a lot cheaper than normal even though the shopping holiday doesn't start for over a week.

Retailers with a wide selection of electronics offer the best Black Friday tablet deals. We recommend shopping primarily at Amazon, Best Buy and Walmart, and if you find a hot deal at one of those, check out the other two to see which has the better discount.
