Went to the Sonos website today to see about their upgrade offer where if you have an old Sonos device they give you 15% off to upgrade to a newer one. Great, or so I thought. They are also running a sale on their website! Sale discount, plus 15% off, right? RIGHT? Well, no. The Arc soundbar RRP is £899 and they currently have £180 off for anyone making it £719. I then go ahead and apply my 15% code on top and.... the cost is £764. Not cool @sonos. Website closed.
