The base/blah etc group have got the three recently released Futurama DVD's at pretty much half the price of anywhere else.
Below are the best prices amongst the group.
With fuel prices skyrocketing, the Planet Express crew sets off on a dangerous mission: to infiltrate the world's only dark-matter mine, source of all spaceship fuel. But deep beneath the surface lies a far stranger place...a medieval land of dragons and sorcery and intoxicated knights who look suspiciously like Bender. So park your hover-car and saddle up your unicorn for Futurama's grandest adventure yet: Bender's Game!
