“What areas is this available in? It says delivery in most areas but not working for any NJ or NC addresses. I tried to order this at the $499 price while it is still in stock, but keep getting a message that it is not available in my area. The item says that it is available for delivery in "most areas" but what areas is that referring to? I have tried our address in NC, as well as family in other areas of NC, NJ, and PA with the same discouraging message.”
