I think he means to say that in the vita warranty on their web site they mention that the spa owner would have to pay for reasonable repairman travel fees and, in the event the spa has to be shipped back to the factory to be fixed or replaced, that the spa owner would have to pay for reasonable shipping fees.
I don't know what reasonable is, but I know it cost me $200 to have my spa delivered from the dealer (10 miles away) to my house.
Only other thing that looked odd is that they can fix your tub with refurbished parts, not new parts, but since the refurbished parts still keep your remaining warranty, it isn't an issue. unless, of course, your dealer actually does charge you for warranty visits.
Some people really care about warranties, others not so much. In the grand scheme of things the chance of you shipping your entire tub back is probably slim. A good dealer will sometimes eat the cost of service for good customers, especially if you keep buying spa products and chemicals from them.
