I've been trying to get help from Seller Central for almost 3 days now in setting up a pre-order listing for a book we are launching. At least 5 associates have assured me they've 'fixed' the problem and the listing should be live within 48 hours. But the three times I've waited the 48 hours (after 3 associates made adjustments to what the previous one had done) nothing works. and we're losing sales. Anyone know how to set up the listing correctly? Thanks
