Hi Jack,
If you go for Option 1 on this page...
LifeFlow® Meditation Technology - Project Meditation
... then, once you've "enrolled" you can send a message to the support team using the Contact Us link at the bottom of any page telling them that you just want LF10 for now. They're very flexible and will put a stop to any further payment being taken and then if you want to move onto LF9 later on, you can just contact them again to start from there.
Hugs
Giles
