These do go on sale for these prices several times per year, but some of them are actually very good in terms of quality if you're trying to piece together a large home theater on the cheap.
SSCS5 - 5" 3-way bookshelf speakers - $74.99/Pair [bestbuy.com]
SACS9 - 10" 115w Active Subwoofer - $99.99 [bestbuy.com]
SSCS8 - 4" 2-way Center Channel Speaker - $74.99 [bestbuy.com]
SSCS3 - Dual 5" 3-Way Floorstanding Speaker - $99.99/Each [bestbuy.com]
SSCSE - 4" Atmos Enabled Elevation Speakers - $99.99/Pair [bestbuy.com]
The SSCS5 Bookshelf, SSCS3 Floorstanding are both a great quality for the price
The 4" Center channel is good for the price, but not quite as great as the above.
The SSCSE Atmos speakers are also a great buy if you're able to wall or ceiling mount them.
Stay away from the SACS9 Subwoofer as it's very plasticy and doesn't sound great.
All BestBuy products qualify for extended return policy through January 16, 2021
