Manga and American Football

First a question - anyone know a decent shop in the UK for manga? Forbidden Planet keep being ridiculously late and behind, but I'd rather by from a specialist than from Amazon, which is my fallback.

Secondly ( Tsubasa Reservoir Chronicles Squee (spoilers for everything up to and including volume 17) )

Basically - eeeee! There shall be thoughts on 18 and 19 at some point in the future.

As to the American football, who should I be trying to convince people to cheer for at our Superbowl party?
