Walmart continues to offer the Kensington Underdesk Comfort Keyboard Drawer, model no. K60004US, for $24.99. Opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with our mention from two weeks ago as the lowest price we've seen. (It's also a current best by $13.) It features a 26" wide tray, wrist rest, mouse pad, and cable management system.
