Next cheapest I can find is £8.69 for this classic 80's Comedy Series
Begin with a Fem-Libber, an American heiress, a not-so-quick school chum and an incorrigible flirt. Add an eccentric romance novelist and a parade of gentlemen callers. Toss in a dash of lunacy and you get the Girls On Top!
Meet Amanda Ripley (Dawn French), Shelley DuPont (Ruby Wax), Candice Valentine (Tracey Ullman) and Jennifer Marsh (Jennifer Saunders), the unlikely roommates who share an apartment under the watchful eye of landlord Lady Carlton (Joan Greenwood). Whether it is a mysterious death, a singing tadpole or nuclear war, these girls find trouble at every turn.
This release features the complete first and second series.
