Yes, that's their business model.
I've never known anyone who's got that far with them, myself.
I see. I didn't know that. And don't really know whether it's significant.
They're a real company, though - they've been around for ages.
All my information about all these places is second-hand, so I can't help much, really.
Like many people with an interest in these things, I have a high opinion of TST and can assure you that they're "the real deal", though.
