The number of credits needed to book a class can change for several reasons, including demand, timing, and promotions. 

From week to week, you may see the same reservation listed for a different number of credits than you did the previous week as demand for the class changes, or depending on how close to the start time of the class you're booking. 

Businesses on ClassPass may choose to dynamically price their spots on ClassPass based on the popularity of a certain class, or choose to make time-limited promotions depending on how often a customer has visited their studio before. 

Alternatively, you may be part of a research and development initiative where we evaluate different promotional offerings. Watch our social media for contests, giveaways, and other fun promotions!
