With price and stock varying by ZIP code, Lowe's offers the Project Source 2-Outlet Extension Cord 3-Pack for $1.99. Choose in-store pickup to dodge the $79 delivery fee. That's $0.66 per extension cord and about $25 less than you'd pay for similar cords at your local Walmart. This 3-Pack includes one 6-foot, one 9-foot, and one 12-foot extension cord.

Update: Specs updated.
