When you order the subscription, it is separate from all other sales. You manage the subscription online. I cannot order it for you, but I'm happy to help if you need it.
Because it is a separate program, the subscriptions do not count towards anyone's party; you do not get hostess credits. CTMH could have let the orders count towards a party - but instead, chose to give you that credit immediately, in the form of a lower cost.
All the current period layouts are shown online, prior to ordering - no surprises! You will also receive an email before your next charge, and can cancel anytime between payments.
If you would like to see what comes in a pack before you actually order, my subscription should be here next week. Pop over on October 20, at my next crop, to get a hands on look for yourself. Or click here to get started!
Happy scrapping!
