Academy has the JBL Clip 3 bluetooth speaker for $39.99 with free shipping. I know this isn't the lowest this speaker has been, but it's by far the best deal I have found in a while. I couldn't find any cheaper even on Ebay. The product page says the Clip 2, but the pic is of the Clip 3, and the item number is the 3. Available in black or grey.
Rugged and waterproof, the JBL Clip 2 IPX7 Bluetooth Speaker can go just about anywhere with you. Simply clip it to your belt, bag or backpack and enjoy your favorite music out loud. The microphone lets you take hands-free calls, and wireless streaming is easy while you're on the go thanks to Bluetooth® pairing.
