Serveral years ago, Costco offered a two year mermbership at 24 hour fitness for $299.99. This works out to a paltry $12.50 a month, less than half of a regular monthly membership if you bought it through 24 Hour Fitness. The regular membership is $30 a month, after an initiation fee.So you will save over 50%. However, recently, Costco.com has 2-Year 24-Hour Fitness All-Club Sport eCertificate Membership (eDelivery) on sale for $369.99 valid for New Members only.Additionally, Costco.com also has 2-Year 24-Hour Fitness All-Club Super Sport eCertificate Membership (eDelivery) on sale for $599.99 valid for New Members only. One benefit of the Costco deal is that if you buy it, that’s your membership; no haggling over upgrades or amenities, because this is what you’ve got for the next two years.
