Groupon still offers the Photive Artisan Portable Bluetooth Speaker in Green, Lavender, and Orange, model no. PH-BT2020, for $34.99 with free shipping. That's tied with our July mention as the lowest total price we've seen. (It's a current price low by $35.) It features 40mm drivers, a built-in passive subwoofer, microphone, and up to eight hours of playtime. Deal ends September 22.
