Amazon currently has the LG SJ9 Sound bar with Dolby Atmos support for just $876.99. This is a great sound bar to pick up, and while it is last year's model, it is still a great option. Typically, it is priced at $999, so this is actually a really good price for this sound bar.
The LG SJ9 is a sound bar that supports high resolution audio as well as Dolby Atmos. So you're going to get some great sounding audio out of this sound bar. On top of that, LG has also included Chromecast support, allowing users to Cast audio to the sound bar from their smartphone. It does have Bluetooth built-in, as well as WiFi support, so you can choose which way you want to wirelessly share your audio with the sound bar. You can also connect it to your TV using an Optical port on the back of the sound bar and on your TV.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast. If you are not an Amazon Prime member yet, you can sign up for a free trial of Amazon Prime. You'll get 30 days free (if you're a student, you get 6 months), and then it's $99/year (or $49/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
