Welcome to our forum.
They had a "sale" this weekend and each Hot Springs spa came with a special "gift pack" worth $1200. The pack includes- ozone, cover, delivery, cheimicals, sub-panel.
I wet tested the Vanguard, and was very impressed with it (although my wife was drowning in it , it was too big for her.) I think you got a great tub and a decent price. You got the ozone, right?
I've had my Vanguard one month now. So far its been working out great (as long as the kids quit messing with the jet adjustments).
