Once sample choice has launched for the current month, you’ll be able to make the selection in your account.
Click “Your Boxes” at the top of the page — then, click “It's time to customize" at the top. You can toggle through the categories and options, and click into each to learn more and make your choice.
You'll receive a confirmation email shortly after you've made a selection. You're able to change or remove your choice until the window closes each month.
