Amazon has this highly rated Vizio Sound Bar (Refurbished) on sale for $99.75. Regular price is $148. I believe that the B at the end of the model number stands for the refurbish grade.
Comes with a 90-day warranty and free shipping. https://www.amazon.com/gp/aw/d/B0794YKVLG#Ask
I bought one recently after reading a lot of great reviews, including one from CNET, calling it "King of the budget sound bars". https://www.cnet.com/reviews/vizi...e8-review/
