Walmart has already announced its Black Friday deals, but now it's following them up with more blowouts for Cyber Monday. As expected, the best deals can be found on TVs, though Walmart says it has over 500 deals for the week starting on Saturday, November 29th — more than twice as many as last year. The best deals will hit on December 1st, however, so be careful when shopping at work so your boss doesn't notice. (Some links will not be live until the deal is available, so be sure to check back at Walmart's site if you can't find what you're looking for right now.)

Vizio officially launched its P-Series 4K TVs last night, which start at $999 for a 50-inch set and go up to $2,499 for a 70-inch set — the first mainstream 4K TVs to be that aggressively priced. To celebrate, the company held a party in a New York art gallery, where the TVs were showcased playing high-resolution video art and in side-by-side comparisons to Samsung's 8500 series, which lists at $2,199 for a 50-inch set. "It's not only shipping an amazingly-priced 4K TV, but one that blows the competition away on picture quality," Vizio CTO Matt McRae told me.
