This could be the mother of all Super Bowl TV sales. Right now, all Roku TVs are on sale at Walmart.

Walmart's sale includes heavily discounted 4K Roku TVs from Hisense, TCL, RCA, and Sharp. Discounted prices start at $115. This is one of the best Walmart sales I've seen so far. (Especially if you're on a tight budget).

Keep in mind that there are many off-brand TVs in this sale. For example, Sanyo, Element, and Hisense are generally not known for their superior performance. However, many TCL TVs are included in this sale, and we are impressed with TCL's 4K TVs.

In fact, the sale includes the excellent TCL 65-inch 4K Roku TV (65R617) for $899. That's $200 off and a great price for one of the best TVs available today. The Editor's Choice TCL 6 Series offers great performance, better backlighting than the previous model, and everything we love about Roku at an affordable price.

Most of the Roku TVs at Walmart include free 2-day shipping, which is great if you're shopping for a new set you can use for big games. Be sure to follow our guide to the best TV deals for other HDTV discounts.
