A4C offers the open-box Logitech Ultimate Ears Boom Portable Speaker in Night Black, model no. 980-000678, for $129.95 with free shipping. That's $10 under our mention from three weeks ago and $40 below the lowest total price we could find for a factory-sealed unit. (Most stores are now charging around $200 for a new one.) This wireless speaker features a 3.5mm auxiliary input, NFC, and up to 15 hours of music per charge.

Note: This item is new but doesn't ship in the original retail packaging. A 90-day A4C warranty applies.
