Currently on JustFor.Fans if you raise your subscription price, your existing customers will be allowed to keep their monthly subscription price until they unsubscribe. If they unsubscribe, they will have to re-subscribe at the new price.
If you want to force all of your customers to re-subscribe at your new price, you can email us and we can turn off subscriptions for your account completely. After all subscriptions have expired, we can turn them back on and they will all need to resubscribe at your new price per month.
