I'm setting up a mini-theater around a new TV (Sony Qualia 006 -- AWESOME !!!) in our game room. The HT400 would be perfect for this rig.
If the MSRP price is $3000, I assume wholesale pricing is about $1500. Discounted purchase price would probably be in the $2400-2700 range, may be a bit lower from John

No doubt Wal-Mart would negotiate a lower wholesale price based on high volume purchase, probably $1200-1350. They could then sell to the customer for $1500-1800 and still make money. Maybe sluggish sales through the typical distributor/dealer network have prompted SLS to look to Wal-Mart as a distributor ?
I have seen many high ticket items in the local Wal-Mart and Sams Club here in Scottsdale (not sure if that is the case everywhere though), and a $1500 speaker system would certainly not be out of the ordinary.
