For in-store pickup only, Kmart offers the Logitech X100 Mobile Wireless Bluetooth Speaker in Red, model no. 984-000389, or Green, model no. 984-000373, for $10. Even better, Shop Your Way Rewards members earn around $5 in SYWR points. (Not a member? It's free to join.) Assuming you'll use the credit, that's tied with our our mention from a month ago as the lowest price we've seen. (It's the best deal today by $11, factoring in the credit.) It features Bluetooth with a range up to 30 feet, a built-in microphone, on-board controls, 3.5mm auxiliary input, built-in rechargeable Li-ion battery, and wrist/backpack cord. Deal ends December 24.
Of note, Shop Your Way Rewards members may be eligible for additional credits and discounts.
