Found a bunch of JBL Clip 2 - waterproof portable speakers on sale in Austin Tx. Red and black. Found them locked in the speaker cabinet and plenty left. Brickseek shows all of austin on clearance. YMMV everywhere else, but I did a couple of zip code searches and found them at the same price in other states. People also reporting they are finding them for around $11. Target appears to have some on clearance as well. Keep in mind this is for the older model and there will be some of the newer model on the shelves which are regular price. Just dig through everything and happy hunting.
