You must be on an active app subscription to The Fit Foodie app in order to purchase the discounted 4-pack. Make sure that you have created a log-in on The Fit Foodie app in order for us to verify your subscription internally. Once you purchase your pack, please allow up to 24 hours for the package to apply to your account (it's usually faster than that... email Amanda at info@amfitnesscycle.com to let her know that you purchased if you need to book ASAP). If you purchase the discounted 4-pack and do NOT have an active subscription, the class pack will not be applied to your account. So don't do that!
