I have just had a look on the Sarik website, and they don't seem to be listing the Traplet Books catalogue.
I cannot seem to find them in a Google search, apart from odd listings in other hobby stores.
Firstly, does anyone know if anyone has taken over this part of the business, and who?
Second, if not it may be worth getting on to Amazon quick and buying any of the books you had your eye on before the price goes up, or they disappear altogether.
