To use a coupon code to sign up for Knit Camp, you must create your account on the WEB APP (not the iPhone or Android app) first. The App Store and Google Play Store do not allow coupons. If you are signing up with a special coupon code, you will need to go to the web app here to register and use your code: https://knitcamp.oliveknits.com/  (Again, do not download the app for iPhone or Android until your subscription is complete.) You must register with the web app first and once your subscription is complete, you can download the phone app to your device, if you would like. We cannot offer refunds if you register or renew without your coupon code, so if you do run into a problem, please reach out before you complete the renewal so we can help. If you're having technical difficulties, we will honor your coupon code, even if it has expired, so don't worry.
