I'm pretty sure it's a grey area as long as it doesn't conflict with Klipsch. We offered this kind of a deal on the other introductions from Parasound over the last couple of years. The Halo sale a couple of years ago was highly successful and many Klipsch forum members benefited greatly. If you are not interested, its no big deal. Just don't spoil it for the rest of the members.
