Walmart offers this 3-Piece Glass L-Shaped Computer Desk in Black (pictured) or Silver, model no. D51Z29, for $79 plus $9.97 for shipping. (Free Site-to-Store is also available.) Even with shipping, that's the lowest total price we could find in either color by $57, although we saw it for $15 less during Black Friday week. Sales tax is added where applicable. This desk is made of a steel frame with a 6mm tempered safety glass surface. It features a sliding keyboard tray, CPU stand, and more.
