I've come to the conclusion that in most instances I'll let 'life' teach people lessons about most things, and not spend too much time trying to correct perceptions. I'll deal with them after they've had a perception correction that they got elsewhere.
In this instance I'd likely tell people to check around more and see if they can find as good or better a domain for their purposes, for the same or less $. If they can, good for them. If they can't, then they'll more likely come back with some purchasing expectations that are more realistic.
It's an approach that's worked for Me so far - My personality and My situation.
