The cheapest Fitness First membership you'll ever find, $15.95 p/week lifetime, great for someone who works in the city, or someone who lives close to one of the Platinum membership gyms. No lock-in contract either. See FF's platinum membership information page to understand which gyms are available to the Platinum membership. Each Platinum gym has unique features, some are 24 hours and some aren't, please do your research. I'm moving to a new gym and no longer need this but wouldn't wish for this price to go to waste. If you are already a Fitness First member, you are eligible to take this rate also.
