We can't actually start subscriptions from our end of the system, so you'll want to do so through the Pathfinder Adventure Path Subscription page. There should be the option to start there with #121. It will likely go to your sidecart by default so it wouldn't ship out until your next round of subscriptions. If you'd like it sent out sooner, just let me know and I can move it into a separate order for you.
I hope this helps! Please don't hesitate to ask if there are any further questions or concerns that you may have in the meantime, and I'll be more than happy to assist you.
Thanks, and have a great day!
