You can start with a free trial period of 14 days which is exactly that – free!
After that, you can choose to pay monthly (£8.99 / €9.99) or yearly (£69.99 / €79.99) at a reduced rate. Once your free trial ends, you’ll be charged for your chosen membership and then charged monthly/annually thereafter.
These subscriptions are rolling plans, so to part ways just cancel. No biggie!
