Massive amazon sale. Price error? I don't know. Good sounding devices? I don't know. Is this too big of a discount to not impulse buy? YES.
Buy first, think about decision later in the day.
Update:
All Speakers and soundbars sold out, only 1 SKU remaining:
Bose Smart Soundbar 900 $225
Thanks, got the Bose Smart Soundbar 600 for $81. Normally a $799 item.
