Walmart, Target, and Amazon have great deals on 4K smart TVs this weekend

The weekend after the Fourth of July is always kind of depressing — because once that peak summer holiday is over, time flies, baby. While winter seems to drag, you can blink once in summer and suddenly, it's September. 
No need to mope around, though: There are a ton of great smart 4K TV deals this weekend that are sure to cheer you up (and give you something to look forward to when the weather starts to get cold again).
