Walmart offers the Furinno B&W U-Shaped Laptop Desk in Black, model no. FNBJ-22032-1, for $22. (Amazon charges the same with free shipping for Prime members.) Choose in-store pickup to avoid the $5.97 shipping fee. That's $4 under our mention from last week and the lowest price we've seen. (It's also a current low by $1.) It measures approximately 19" x 12" x 24" and features rolling caster wheels.
