Walmart offers the Techni High Back Executive Chair in Black, model no. RTA-4834-BK, for $42.50. Choose in-store pickup to dodge the $4.97 shipping fee. That's $7 under last week's mention and the lowest price we've seen. (It's also the best deal now by $29.) It features high-back molded armrests, adjustable height and tilt, and nylon casters.
