Mr Juddery and Ms Deane said the books appealed to a wide audience and said punters were purchasing them for a range of different people.
Also topping the list, following the release of the latest Star Wars movie this week, is anything and everything to do with the film. Neil Lambess manager of Replicant Hobbies said the day after the midnight release of Star Wars: The Force Awakens he had about 300 people through the store, which he said is busy for a little local shop. "It's always popular but more so after the release, in fact we've nearly run out of stock."
He said the Star Wars kitsets were doing well, but the Millennium Falcon set was number one on shoppers' lists. "You get some kids in and you ask them if it is for themselves or a present and they'll say, 'No it's for my dad,' and then you ask others if they are buying it for their dad and they say, 'No it's for me.' It's really popular with all ages."
Mr Juddery said Star Wars products were also doing well.
In terms of popular books, Mr Juddery said Dan Carter: My Story, Chelsea Winter cookbooks and books about different YouTubers and bloggers, were selling fast. "It's amazing how well the vlogger (video blogger) books are doing," Mr Juddery said.
On the technology front, FitBit, a wristband that monitors fitness by connecting wirelessly to a mobile phone, is popular again this year and the top three console games are Destiny, The Last of Us and Minecraft.
