Youre not really serious about buying a spa sight unseen, and not being able to touch it, sit in it, etc are you?
Thats like seeing a mattress set on tv or online, being told orders are only done via phone/internet and cant try them out. So you do, it arrives, and you dont like it.
Can you return the spa if you dont like it, without a restocking fee? Who is going to fix it in your area?
Stick with the local folks, and get better support, service, and a brand you can trust.
