CellularFactory offers this Coolball Laptop Cooler Ball Stand 2-Pack in Black for $1.99. Bag free shipping via coupon code "12BSP6". That's the lowest total price we could find by $1, although we saw a set for a buck less in November. This set includes two cooler balls (enough for one laptop). They attach to the bottom of your laptop to elevate it and create more airflow. Coupon expires January 16.
