Walmart offers the Stanley 40-Piece Socket Set for $19.99. Choose in-store pickup to dodge the $5.99 shipping fee. (Home Depot and Target both offer it for the same price.) That's the lowest price we could find by $11. This set features a full-polish chrome finish, anti-corrosion protection, 1/4" socket driver handle, and 3/8" pear head ratchet arm.

Update: Pickup is no longer available at Walmart; however, Home Depot and Target still offer it for the same price.
