Sonos discount code

I am looking for a Sonos 50% discount code. Planning to buy bunch of speakers, sub and fully utilize 2.5k worth of purchase. Already purchased 2.5k, but only got 5.1.2 setup with Arc. Need more speakers for additional rooms and one more sub. I am hoping it's still good business for Sonos. One could say I can afford and buy at full price or lesser discount that company offers. But you only biundo much with 🍌🍌. Please help, if you can. DM me.
