White Knight Design - various geeky movie-inspired prints and stuff
Panda Island - "My Panda Island offers a cute and quirky range of comic, film and kawaii inspired jewellery, accessories and homewares."
Coasteroo. A "selection of film and TV themed coasters".
Comic Parade. Apart from being a comics, toys, DVD & Blu-Ray shop and therefore being metaphorically right up my street, this is also in Watford, so although it's not literally right up my street it's no more than a half hour's drive away...
