If your first box is the Editor's Box, you'll have a chance to purchase add-ons right after you create your subscription! (What's an Add-on?) Once you've filled out your shipping address, you will have 15 minutes to shop our new member add-ons. If the time runs out, you'll be able to purchase add-ons beginning with the next season's box! New member add-ons are completely optional and you can skip this step of sign up if you'd like!
