Sears offers the Bem Wireless Mobile Bluetooth Speaker in Black, model no. HL2022B, for $29.99. Choose in-store pickup to dodge the $6.50 shipping fee. That's $20 below our November mention, which included a $40 Sears credit, and the lowest price we could find now by $14. It measures 2.5" cubed and features a 25-foot range, 3.5mm auxiliary input and output, and mini USB.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
