Sears offers the Craftsman 3/8" 4-Piece Extension Bar Set

. Plus, Shop Your Way Max members bag free shipping. (Not a member? It's free to sign up
for a 90-day trial; otherwise, shipping adds $6.50. In-store pickup is also available.) That's a buck over our February mention (which required in-store pickup) but the lowest total price we could find by $15. This set includes 3/8" drive extenders in 1-1/2", 3", 6", and 10" lengths.
