With the new website revamp, I seem to have lost my ability to look at my subscriptions. What upcoming items are going to be in them, as well as changing mailing address/options or even just cancelling them.
You should be able to get to it from My Account>Account Settings, which is admittedly unintuitive.
Click on My Account on the top right to bring up a menu, then select Account Settings. After you enter your password, My Subscriptions should be selectable on the right side of the page.
