Today an official website for the Pokémon Center has been opened for the UK market!
The site offers a variety of official Pokémon products including plush toys, pins, clothing and trading cards all available with a flat shipping rate of £5. Although be warned like the US and Canadian stores, the UK store will only ship to UK based addresses.
The stock does differ from the other stores somewhat, but there is still quite a big range available with plenty more forthcoming. If you want to check it out for yourself you can find the website here.
