Norwich On Line

Why cant I get a Norwich ticket on line, I am registered on the data base and have an online purchase history, so unless it's already a sell out, what's the reason?

Norwich have sold out their allocation, hence we have to take the game off the internet as Norwich fans could register and purchase tickets. This is something we are looking to change, but at the moment it is the only way we can stop norwich fans purchasing tickets for the home end. The same will apply for Southampton as it did with Millwall and Leeds. Standard ticketing practice I'm afraid.
