Good Susan!
After your Intro Kit, you are on Auto Delivery and Easy Pay. There is no way out of that. I recommend that you immediately set your deliveries for every 20 weeks until you become familiar with them.
Also, give them a good phone number. That's how they recognize you when you call. You get a personal Wen concierge! They don't misuse your phone number.
Check the email address that you give them frequently. That's where all the goodies go!
Get your flu shot...because I didn't.
