Onn is a brand mainly targeted toward budget offerings, so their 50-inch TV is already well priced at $238, a staggeringly low price for a 50-inch 4k TV. Luckily, you can grab it even cheaper at Walmart, where they offer it for just $198. That’s a $40 discount and brings this reasonably great and large TV in the sub-$200 range, and it even comes with a great smart TV platform, Roku, so you don’t have to spend extra money on a streaming stick for a better experience.
