Saw this on their site. This is the purchase page (you need to be singed in).
If you already have a subscription, buying this will cancel the existing one without a refund. Confirmed with customer service that subscribing at the current deal price will lock it in for future renewals.
Paid almost A$79 for it last year. Partner and I use it almost daily for Yoga and HIIT respectively. Good quality app, with very configurable routines, music, different voices, levels of instruction etc. Works with Airplay and Chromecast. Syncs with Apple Health. They are cool with people sharing a subscription within a family/unlimited devices.
