Welcome to our forum.
Also, I doubt you will find a used 2013 A8 anywhere. I would jump on that.
I am currently looking to buy a big hottub and love the A8D. I was told that the A8D is the cheaper of the A8's because there are ony 5 jetpaks. I have a price quote of 14295 less $500 (for labor day) and another 10% off for taking the demo one they have in stock. Still, this comes to 12365.50 plus tax so $13,285 total. This includes delivery, steps, cover, and the thing that makes it easy to close the cover. It does not include the extra $1,025 for the electrician to come set up the 200 watt. I see some people on here getting much better deals. Any advice?
