I managed to get 15% off a new Black Sonos Beam (Gen 2) directly from Sonos.
I have 2 Sonos Play 1's registered to my sonos
account which made me eligible for a 15% reduction on selected Sonos products, including the Beam (Gen 2).
This makes the Sonos Beam (Gen 2) in Black the cheapest I have seen.
As of November 2020, Sonos has introduced a new Upgrade Program that allows long-time Sonos owners to buy new Sonos speakers and get a 15-percent discount
. This is not a trade-in program; you'll still keep your old Sonos speakers
