My promotional subscription was supposed to end tomorrow, so I tried this in an attempt not to get price gouged. To my surprise, IT ACTUALLY WORKS!!!
My previous subscription was for SiriusXM Select for $30 for 6months($38 after taxes&fees). And after that, it would have increased to $20/month(nope). First the rep tried to sell me on SiriusXM AllAccess for $12.99/month. Definitely wasn't going for that offer because on top of having more features than we needed, I'd still be paying substantially more for the service. Next offer was SiriusXM Select for $40/6months($60.77 after taxes&fees). Not a terrible deal, but I reminded the rep that I have both Amazon Prime & Xfinity that have their own music services that I could fall back on. Then after putting me on hold for a bit, he came back at me with SiriusXM Select Lite for $30/6months($37.95 after taxes&fees). It sounded good, but apparently they recently created this package level and it doesn't include streaming over phone/tablet/computer. I told him I'd already been using the app on my phone(I actually have!) and that I wouldn't be comfortable paying the same amount for less features than I was currently receiving. After a few more minutes on hold, the rep came back with the offer of SiriusXM Select for $37.95 for 6months(after taxes&fees). All of the features I currently have for the current promotional rate I had before. SUCCESS!
So I bit on the offer. Who knows how much lower they were willing to go. But with my current rate's end rapidly approaching, I certainly wasn't willing to test my luck. This was my first ever attempt at this. Thankfully, I had an amiable person on the line today, who was very kind and courteous. Good luck, everyone!
And thank YOU, OP, for this awesome information!
