The Sonos Era 100 SL speaker is $40 cheaper for the last hours of Amazon's Prime Day sale.
Amazon is selling the Era 100 SL for 21% off its normal price as part of Big Deal Days, which ends at midnight. The discount applies to the speaker on its own, not a bundle. Sonos positions the Era 100 SL as an add-on speaker, the kind you pair with a soundbar or another Era 100 SL to fill out a home theater setup rather than a standalone centerpiece.
A 21% cut sounds solid until you remember Prime Day throws out dozens of smaller audio markdowns an hour, most of which barely change the long-run price-per-use math. Sonos rarely discounts its own hardware directly, so even a modest $40 drop is one of the few windows to buy below sticker price without waiting for a holiday sale.
If a home theater upgrade is on your list, the ticking clock - not the size of the discount - is the real reason to act before midnight.
