For every Ortho Home Defense Max Pest Control Wand you buy (Item# 2842), you get a free ORTHO Home Defense Insect Killer for Indoor and Perimeter Refill (Item #618033) automatically added to your cart for in-store pickup.

The Wand kit is selling for $13.27 in my area and then you get a refill for $9.99 for free.
