Anker finally officially released their SoundCore Pro. This is their first new Bluetooth speaker in quite some time. A couple people have already purchased it in their local Walmart stores. Reportedly, it costs $100 there. On Amazon, it is currently available for $90 (the pictures have just been updated and the product description looks correct). For updated pictures and additional information, view the Anker product page here.
But, you can find it much cheaper on eBay RIGHT NOW (if you're fast). A seller with a 99.6% positive feedback rating currently has it listed at $49!!! Heck, you may be able to resell it at that price, but it sounds like it's a pretty good speaker. It's up to you, but seems like an incredible deal. Of course, it will almost certainly be short-lived, but I would jump on it now if I were you! There is only one available.
There is also an active auction that is currently at $40. You can view it here.
Thank you and have a nice day!
