This foldable desk is a perfect option for travel.

The
Green Forest Portable Laptop Desk is available for just $18.74 at Amazon when you enter promo code
GTA7KU2H during checkout. This desk was selling for $30 up until this past January, when it started becoming available around $25. It's only been available below $20 a couple of times in the past, so this is a pretty uncommon price drop. Both the beige and white versions of this desk can be discounted with the code.
