For in-store pickup only, Sears offers the Accutire Digital Tire Pressure Gauge, model no. MS4021, for $9.99. Plus, Shop Your Way Rewards members will receive about $10 in SYWR points. (Not a member? It's free to join.) Provided you use the credit, you're essentially getting the gauge for free. (It's a current low by $11; we saw it for $7 via pickup in May.) It features an LCD display and lithium battery.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
