Walmart offers the ONN Full-Motion Tilt/Swivel Universal Wall Mount Kit for 19" to 84" TVs with 10-Foot HDMI Cable for $39.99 with free shipping. That's tied with our February mention as the second-lowest price we've seen. (It's the best price we could find today by $7.) It features a 12° up or down vertical tilt, 180° horizontal swivel, and 132-lb. maximum weight capacity.
