On The Market - add the Sonos Sub Gen 3 (white or black) to cart. It's listed as $1299 in the search results, but is $999 in cart. Add coupon "BF10" for $99 off - $900. Works out to $905.10 with the $6 shipping.
EDIT - Looks like the Product Page (both colors) now shows $999, but the search results are still $1299. Looks like Pricespy also picked up the new price.
It appears all the sonos product prices havent updated on the product page but updates in the cart to match what’s advertised on the noel leeming site. E.g. the arc is $1399 and beam 2 is $699 when added to cart
I wonder if there are other noel leeming products on the market with the same bug
