While researching the purchase of a HDTV online, I see that viturally all the online dealers (with best prices) are in the NY/NJ area. Many on the same street and a few even with the same address. Why is there such concentration of dealers in that area and no where else in the US? If its cargo ship import proximity, I would think there would also be large concentration of dealers on west coast where most of the far east imports go. Is there a reason for this? Many of the dealer have reaonably well done websites and state US Warranty and Factory sealed units. All show up on the Pricegrabber, CNET et all websites and most with reasonable feedback ratings. But still wondering if the price is too good to be true and somehow related to this unusual concentration of online dealers. ANy experience in this area to share?
