For in-store pickup only, Sears offers the Craftsman 4-Piece 3/8" Drive Wobble Extension Bar Set, model no. C44284, for $6.69. That's $5 under last month's mention and the lowest price we've seen. (It's the best deal now by $10.) The set includes 1-1/2", 3", 6", and 10" extension bars.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
