Nautilus replacement wooden deck for Revell VII-C 1/72 U-boat kit (kit #5015)?

Hey guys....I am assembling aftermarket parts for the above Revell kit and was so pumped to find a beautiful replacement wooden deck offered by Nautilus, but although I can click on the two items I wish to purchase from their U.S. Order page on their website, there is no cart page or check out page shown.  I also cannot get a valid email address, and they do not list any phone number.  What gives?  Are they out of business?  If so, do you know where I can find one of their wooden decks for my sub?  (I came up empty on Ebay...unless I did not describe it adequately...)   Help!   Robert from South Dakota
