Sears offers the Craftsman 65-in-1 Universal Multi-Tool, model no. 35455, for $9.99. Opt for in-store pickup to dodge the $6.50 shipping fee. That's tied with last week's mention as the lowest price we've seen. (It's also a current low by $14.) It can be used for eight standard and eight metric fastener sizes.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
