Walmart offers the Mainstays Deluxe Laptop Cart in Black for $32.92. Pad your order over $35 to bag free shipping; otherwise shipping adds $5.99. (Free in-store pickup is also available.) That's the lowest price we could find by $13, excluding padding. It features a 5-position adjustable main work surface, fixed side table, and adjustable height.
There are plenty of great ways to spend your money, but you can safely leave these products on the store shelf.
