For in-store pickup only, Kmart offers the Ortho Home Defense Max 1-Gallon Insect Killer, model no. 0196710, for $6.99. That's the lowest total price we could find for one picked up elsewhere by a buck. (For further comparison, we saw it for $2 less last summer.) It's designed for interior and exterior use and purports to kill and prevent ants, roaches, spiders, and other pests.

Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
