To set up coupon codes for your activities, head over to your Profile and choose Coupon Codes under Pro Features.  Lots of possibilities here with this one, so here are a few examples below:

1. Dollar or Percentage Discount - you can provide either!  Choose whichever option you like, or create multiple codes to run promotions for your clients.

2. Expiration (optional) - set expirations to allow promos for only a certain amount of time to provide incentives to clients to sign up during a specific period of time.

3. Usage Limit (optional) - how many times the coupon code could be used before it is invalid.  For example, you could say the first 5 clients to use the code will get $5 off the class!  After 5 uses, the code will be invalid.

4. Usage Limit Per Person (optional) - how many times a coupon code could be used by one person before it is invalid. For example, you could say a user's first class with you is free if they use a specific code.  After the user uses the code once, they could not use it again and this is great for attracting new clients.
