Vius via Amazon offers the refurbished JBL Charge 2+ Splashproof Wireless Bluetooth Speaker in Teal, model no. CHARGE2PLUSBLKAM-Z, for $66.24 with free shipping. That's $14 under our August refurb mention and the lowest total price we've seen for it in any condition. (It's also $28 below the best deal we could find for a new one today.) This 15-watt speaker also functions as a portable battery pack and features a 75Hz to 20kHz frequency response, two 1.5" full-range drivers, built-in microphone, water-resistant silicone coating, and rechargeable 6,000mAh Li-ion battery with up to 12 hours of playback per charge.
Of note, PrimeDeal via Amazon has it in Blue, and Chubbiestech via Amazon has it in Black, both for $69.99 with free shipping.
A 90-day warranty applies for all three items, but it's unclear who covers it.
