If you want to view what's in your box during your shopping window all you need to do is click the pink Customize button on your account page and then click the green box icon in the upper right corner.
Once your shopping window has closed for an order you can find the list on your order invoice on the Order History page of your account.
To view your order invoice:
Step 1: Go to "Order History" under the "My Account" menu
Step 2: Click the grey "View Order" button for the order you'd like to review
This will open up your order invoice. The total order amount and method of payment will be listed at the bottom of the invoice.
