Bought a Martinique (5 person) spa – Jim told us it was too big for us and suggested we get a smaller (cheaper) one. When is the last time a salesman suggested you buy down? BTW: he was right, it is too big for just two.
Ditto chemicals: New Products has a variety of chemicals I can buy, but he suggests only 3 (chlorine, shock & soda ash) plus a “silver stick.”
Knowledge & experience are obvious because of his (and Jay’s) years in business. e.g. he can build you a wood hot tub.
After sale service is most important and NP has it, and keeps the cost down by having parts in the truck (saves a second visit cost).
Remember when shopping to take your swim suit and wet test, listen to the motor noise, note egress & ingress. Obstacles killed our other choice.
Everyone else’s comments are spot on.
I will shop there again.
